Overview:

Close Support Bridges (CSB) are basically deployable bridges that you can place over a river, ditch and many other obstacles in order to cross them at locations that possibly your enemy might not expect. This means your team is no longer purely reliant on normal bridges and even if a bridge is destroyed, you can still cross that bridge by setting a CSB over the damaged gap of the bridge or by placing a CSB next to where the old, destroyed bridge was.

How ever you can't just go around deploying these bridges where ever you feel like it. The conditions for deploying these bridges needs to be just right in order for them to work. Although this dose include most stretches of river, ditches and other obstetrical which you might need a CSB across. We have achieved this by setting up pre-defined CSB locations, at every possible location the player might want to deploy a CSB, providing a CSB would work there in terms of realism and operability. This is not to only make sure that these bridges can't be placed in such a way that could be exploited, but also to make sure all the bridges match up and vehicles can drive over them fairly easily :)

So far we have crated the BR90 Family of Close Support Bridges (CSB), which in real life are used by the British Army. Ingame these CSBs will be used by all conventional factions (British Army, US Army, USMC, Russian Forces, PLA, etc). Even thou in real life most of these factions use there own unique set of Close Support Bridges (sometimes also named differently, but they do the same job) we felt that it was best to get one type of bridge in first and then possibly in the future look at making different types of CSBs for other factions. We chose the BR90 family of Close Support Bridges (CSB) since we could get the most refs for all of them and we knew fully how they worked and are around the most flexible CSBs as well. Crating other factions Close Support Bridges (CSB) in the future is not very high on our list for things to do so I can't say when or if we will ever get other factions CSBs in the mod.

That said, for the BR90 CSBs, we have crated 3 types of bridge sections, which ends up becoming 8 different versions giving us lots of flexibility with how we can use them.
Image
On the top row we have the No. 10, BR90 CSB which is a 22m long scissor bridge that unfolds when its deployed (in real life, ingame you will unfortunately not see it unfold due to engine limitations). There are 3 versions of the No. 10 CSB, the first one on the left just being the plain No. 10 bridge, the second one in the middle being the "sds" version, where sds stands for Single Dirt Support and then the 3rd version on the right being the "dds" version, where dds stands for Double Dirt Support. These dirt supports, like on other deployables allow us to easily place them where ever we want but they also signifies to a player where a bridge starts/ends and where they can start deploying bridges from. We will get more into that later in the CSB deployment tutorial.
In the middle row is again the No. 10 CSB, but this time with a Trestle Attachment which allows for combination bridging. Combination Bridging is needed where a river is too wide for one single bridge section to cross it, so you can instead place a No. 10 Bridge with a Trestle attachment to allow for multiple bridge sections to span a river, since the trestle acts a support coming out of the water. Again we have the normal version without any dirt supports and we also have a version with a single dirt support. The double dirt support isn't necessary here.
On the bottom row we have the No. 11 CSB, which instead of being a scissor bridge like the No. 10, its a up and over bridge, as it dosen't have the folding section of the No. 10 bridge. This bridge is 15m long and also has both the sds and dds versions, and is used for small rivers, ditches and it can be used in combination bridging.


In real life CSBs are deployed by a specialist bridge laying vehicle, such as an Armoured Vehicle Launched Bridge (AVLB) such as the TITAN and the M60A1, but CSB can also be deployed via a Tank Bridge Transporter (TBT) which is pretty much a Truck that can carry and deploy CSB.
Image
Ingame we are not have any of these specialized vehicles for quite a simple reason, we do not have enough players ingame to crew bridge launching vehicles with also carrying out all the other tasks required ingame already. As such we have simplified it by giving the task of carrying and deploying these CSBs to the logistics trucks since they are pretty close to a Tank Bridge Transporter, other than you cant see a huge section of bridge on the back of them and it gives the Logistics truck anouther useful role ingame to encourage players to play that role more.
The Logistics Truck will still do all its old jobs of deploying supply crates and giving repairs to damaged vehicles on the field but also on top of that, it will be able to deploy a CSB.
You will now have to choose between deploying supply crates or deploying a CSB, you will not be able to deploy both in one trip, so don't try :p
A few modifications have been made to how the Logistics Trucks work now so be sure to check out the tutorial below on how to deploy CSBs to see what they are.

How To Deploy a Close Support Bridge (CSB)


Since our CSBs are going to deploy very differently from our other deployable objects I'm going to write a small tutorial here on how its done :)

First of all you will need to grab a Logistics Truck on a conventional forces team (Militia, Taliban and Insurgents don't count), the logistics truck being the truck with the canvas over the back, for the British its the MAN truck with the canvas over the back. You can also check your Truck can deploy bridges by scrolling though the weapons and checking it has a CSB in the selection list (default key: 4). Also note with the new selection list in the logistics trucks that we have also added a "Nothing Active" weapon in slot, this is basically a safe mode to make sure you dont drop crates while on the move. We have also moved the Supply Crates to the 2nd slot (default key: 2) and added the repair drop into the selection list (default key: 3):
Image Image
Once you have a Logistics Truck that can deploy a CSB, drive to a spot where you can deploy a CSB. You will be able to tell where a bridge can be deployed most of the time by a small dirt pile on the river bank or on the side of a ditch etc or in some cases there will be no dirt pile reference like when deploying a CSB over a broken part of bridge.
Image Image
Now backup your logistics truck up to the place you want to deploy your CSB so that the back is facing towards where it will be placed and get it as close as possible to make sure it deploys, deploy it too far away and it will not work and you will need to go back to base to reload your CSB again so don't be afraid to get out and check your close enough.
Image Image Image
Once you have backed up to where you want to deploy your CSB, select your CSB from your weapon list (default key: 4) and click the right mouse button (RMB) to deploy the bridge. You should hear the sound of hydraulics working but you will have no visual que for the CSB being deployed other than with the CSB "weapon" selected (default key: 4), you will see the "2" in the bottom right hand corner turn to a red "0".
Image Image
A few seconds later (can sometimes take as long as 10secs), if you have deployed your CSB correctly then you will see it appear in front of your eyes, and you will be able to drive happily over it :D
Image Image
Image Image

For combination bridging, when spanning larger stretches of river you basically need to do the same things as when just placing down one bridge, but since you are deploying multiple sections you need to do it more than once.

First of all like before grab your logistics truck and drive to a location where the gap that needs to be bridged is large enough that it will take multiple CSBs to bridge and back your truck up to it like before.
Image Image
Deploy the bridge like before and you will then see the first section pop up into view like before, the only difference this time that the bridge dosen't meet the other end of the river.
Image Image
Now you have dropped your CSB you will need to Return to Base (RTB) and reload it at the vehicle supply and repair depo. Make sure that you fully reload the CSB before setting off by selecting the CSB in the weapon selection menu (default key: 4) and checking that it has "2" in the very bottom right of the screen. If it has a "0" or even a "1" it will not deploy a bridge.
Image Image
Once you have reloaded your CSB, head back to your bridging project and back up onto the completed section of bridge. This you may find a little tricky, espically since your reversing onto it so I would suggest you also check the driving tut below and also practice driving on forwards first. But to deploy the next section of bridge you need to back up onto the completed section. Use your rear mirror view (default key: F11 or C) and back up onto the bridge. You will most likley want to get out and check just before you hit the bridge that your wheels are in line with each side, if you get it wrong you will slip down the middle and die.
Image Image
Image Image
Once you have backed up onto the bridge and your close to the end you can deploy your new CSB (you can be further away than I am in my last pic, I was a little too close :p )
Image Image Image
And now Mr Tanky can happily cross the bridge you have just completed :D

How To Drive Over a Close Support Bridge (CSB)

Now I know most of you are going to laugh that I've put a tutorial on how to drive over a bridge but I'm going to laugh even harder at someone who didn't read this tutorial who ends up falling off one of these bridges and dies :mrgreen:

First of all I would suggest you first try driving over one of these in a tank, since a tank is the easiest vehicle to drive over one of these believe it or not, simply because these where designed mainly to take tanks in r/l and as a result are the same width as a tank and you have a lot of space to play with, as well as with your driver view being in the very centre of the tank you can easily tell how far off to the left or right you are and how much you need to adjust, but this still dosen't mean you should go over one of these bridges like a bull in a china shop.

First of all drive upto the head of the bridge and line yourself up with the bridge, for your first few times you will probably want to get out and check just to make sure your all good but once you have got the hang of it you wont need to leave the protection of your tank :D
Image Image
Once you have lined yourself up, drive over it slowly, in real life if you drive over these bridges too fast your track can kick out the bridge from under you, although this dosen't happen in game its still a good idea to do so, and just continue strait to the end, making as few adjustments as possible and any adjustments you do make, make very small ones.
Image

Now that was the easy tank, the smaller the vehicle you go the harder it gets because there is very little room for error when driving over these. I'm really not at all surprised when a few months back when a Flood in Workington (NE England) destroyed a bridge and the Royal Engineers where sent in to build a replacement bridge to temporarily reconnect the town, why they didn't opt for these Close Support Bridges (CSB) and only built a foot bridge, because if they did we would have seen car after car falling into the river, but the News Reports didn't seem to get that point :p
Image

Any ways, like with the tank before, first line your front up with the bridge, since on the landrover your sitting far on the right side, you will have yo really compensate your view to get both wheels onto the bridge and you will really need to learn where abouts your wheels are on every vehicle if you want to get over these bridges quickly without checking and making adjustments.
Image Image
Once on, keep driving strait and slow like the on the tank.
Image

If you mess it up, this is what happens and you loose a vehicle and a bunch of tickets, + maybe a few men (note: I messed it up on purpose :p ).

Close Support Bridges (CSB)

FAQ:
Question:
Silly_Savage wrote:I do have a question though. Are the locations where you can place the CSB predefined on every map? There's no option to place them where you want?
Answer:
[quote=""'[R-DEV"]Rhino']Ye they will be, although we have yet to mark out the pre-defined locations on every map (a few maps will have no locations for CSBs as well) and the current locations on Al Basrah will most likley be redone as well since Al Basrah was our POC (Proof Of Concept) map for this idea and I rushly placed a few positions as we needed them hehe :)
[/quote]

Question:
[quote="dtacs""]Can the bridge be destroyed in the same manner as FOB/FOB assets with an incendiary grenade, or repeated armor piercing/HEAT fire?
Answer:
[quote=""'[R-DEV"]Rhino']No the CSBs can not be destroyed by Incendiary grenades, but they should be deployable by a few MBT SABOT/HEAT shells but I have not tested how many. Basically they use the same materials as a normal destroyable bridge dose so w/e destroys them can destroy this :) [/quote][/quote]

Question:
[quote="dtacs""]Theoretically if a firebase is within 150m of the bridge, can I deploy TOWs or HMGs on top of the bridge?
Answer:
[quote=""'[R-DEV"]Rhino']Yes, but it wouldn't be a good idea since the crossing is more valuable than the emplacement location I would have thought.[/quote][/quote]

Question:
[quote="dtacs""]If someone is near it, can you be killed by the bridge being deployed, similarly to what happens with the current FOBs?
Answer:
[quote=""'[R-DEV"]Rhino']I can't say I've tested that but I do not think so no. You will defiantly not get the same "being crushed" effect you do with a normal deployable and I think the most you will get is a guy with a bridge though his rib cage, but if he goes prone he can get out of it kinda thing hehe.[/quote][/quote]

Question:
[quote="dtacs""]Can the dirt piles be destroyed by an ArtyIED or the like?
Answer:
[quote=""'[R-DEV"]Rhino']No, the dirt supports are indestructible[/quote][/quote]

Question:
[quote="dtacs""]Whats stopping Insurgents by placing mines just in front of the dirt pile such as below:
http://img294.imageshack.us/img294/6709/minescopy.jpg
Answer:
[quote=""'[R-DEV"]Rhino']Nothing, they are also new IED hot spots, pre-determining where a bridge might be deployed, before its deployed could lead to getting a tank in the river if you let them build it and wait for them to use it ;) [/quote][/quote]

Question:
[quote="dtacs""]If the spontaneity and random placement of bridge buildings is removed by the dirt piles, does that not defeat the purpose if they can still be booby trapped?
Answer:
[quote=""'[R-DEV"]Rhino']I'm not 100% sure what you mean there, can you rephrase the question?

But the idea behind this is not excatly to make it impossible for IEDs to booby trap them or anything like that, the main thing from this is to be able to attack the enemy from an unexpected angle :) [/quote][/quote]

Question:
[quote="Fighter""]Is there a limit to how many segments may be deployed out of one truck even with RTB'ing? Apologies if I missed this in the text.
Answer:
'[R-DEV wrote:Rhino']no there is no limit other than how many pre-defined CSB locations there are on the map.

Excellent work!

I do have a question though. Are the locations where you can place the CSB predefined on every map? There's no option to place them where you want?

i can see many exploits coming out of this, like putting them over mine fields possibly, but besides that its very cool!!

good work

CSBDEPLOY squads shall now be my new found habit. Is there a limit to how many segments may be deployed out of one truck even with RTB'ing? Apologies if I missed this in the text.

One segment before RTBing, so a good idea may be to take more than one supply truck. Unfortunately CSB squads may take more than one leaving the rest of the team without supplies for FOBs, so adding more trucks might be a good idea.

These are made to avoid the current destroyed/booby trapped bridges right? But what is the point of the Insurgents already KNOW where the bridges can be placed? Can't the whole length of the river be one big dirt pile?

I'm thinking they're more like emplacements to replace the normal bridges if they're destroyed, rather than ways to avoid IEDs and the like.
