1. Sometimes bodies gets flung too far away from their "kit" which makes them un-ressable or they get glitched somehow. Resuscitate is used to fix that but in my experience it's better drop a field dressing on the body, which also heals the player when you EpiPen them.
2. The cap range scales with the size of the map, iirc the numbers are 75m for 1km? maps and 150m for <2km? maps. The squad leader can't see, but there needs to be two people inside cap range for the flag to be capped. Pressing the map key (M) or kit key (Tab) and looking in the top right will let you see if you're capturing or not by watching the little blue slider move. If it doesn't that means that there are enemies contesting the capture.
3. The vehicle squads are crucial for the success of the team and to operate the vehicles require extensive knowledge and practice. Each vehicles is effective against some things and vulnerable to others which takes months to learn and years to master. If you want to join those squads then i suggest picking infantry classes that is meant to combat them, such as Light anti tank and Manpad (Anti air) so that you learn what you're weak against and names of the vehicles, btr's, bmps etc.. Playing on practice servers untill you're comfortable with vehicle is good too. When you think you're ready join an APC squad on an insurgency map or an aas map with light armor and request a gunner position, it's relatively easy and won't affect the team too much if you screw up once or twice.
I do recommend though that you try to get into armor squads, knowing that you're the baddest son-of-a ***** on the battlefield is fun. ^^
4. Military slang for a civilian vehicle augmented into a military one, the better question is why the suicide truck is called "Gary".
5.Bullet drops exists but it doesn't matter unless your engaging targets above ~500m.
6. The PR wiki (
ProjectReality Wiki - Wikia) has damage numbers for some guns, and the hitbox numbers are roughly:
body armor: 1
Body (without armor): 1.7
Arms & Legs: 1.1
Head: 8
Damage numbers are abit strange since the battlefield engine can only handle fire rates that are preset at like 300, 500, 700, 900 or something (probably not those exact numbers but you get the idea). The G3 has a fire rate of only 500 but has 50 damage per bullet to compensate. Usually the damage of a gun is around 35-50 based the fire rate. Snipers are usually one shot one kill. I go for the guns with the best scopes and handling, which if why i hate the Russians with a passion. (C'mon 1.4)
7. It's delayed slight after a player gives up (when they can no longer be revived).
A tip, when you press tab, you can move the cursor to click on the "logistic" tab above the map, there you can see what vehicles are on the map, so if you see a vehicle but you're not sure what it's called, check there. Calling it out goes something like "(Vehicle name) 300 meters north west, moving towards us."
GL out there.
