People I would recommend
Strktm is great if you can get in the squad
iGi has some good players on voip
danthemanbuddy leads occasionally
Learning wise lets see..
First off is get your settings down, don't want to lag to death or not have voip
Second off is knowing your role - if your a medic for 5 other men don't try and run off in point unless your getting outnumbered...
When you get a good SL try to stick to what your squad is based around ( CO support, infantry, mech inf, HAT inf, armor, air support etc )
Don't spawn spec ops as a base kit if your requesting limited kits, I've heard you don't get body armor on those limited kits after spawning spec ops.
Kniviving rally points is silent, but you can shoot them as well from a far
Keep an engineer and multiple crewman on your armor whenever possible
Try to use smoke effectively and not blind your team.. same with flashes
Don't take a kit you know your going to be poor with... like HAT or sniper when your totally new to it..
Click to heal - lol
Use laser guided bombs on bombers, don't try and bomb with fighter jets ( not enough arms, only short range missiles / LIMITED cannon ammo )
High alt. with attack chopper and TV guided missiles is a good strat when in them..
Remember in jungles slowing down can give you the advantage... such as crouching by a bush and checking your surroundings instead of sprinting until you take fire.
Remember to limit voice coms when trying to be silent "frag out" "follow me" "enemy spotted" ETC
Good servers to play on for the states that I like are DVB & TG
battlearena can get messy if no admins are on
Read the guide about insurgency too much to cover here
Remember on tops of hills you got the old BF2 terrain thing where you "hover" above the hill...
Know what is concealment and what is cover
30 second warmup times on aircraft - and sabot loading time on tanks
Remember you can rearm your field dressings off any ammo source - and rifleman ammo is very very limited
wait 30 seconds before firing HAT, check when scope is up, avoid firing indoors and near corners/poles due to risk of suicide
Remember to load up heat "2" on armor when firing at infantry with APCs / Tanks, don't use sabot on infantry it is very innefective and must be a direct hit
Remember there is small bullet drop on coax, larger on marksman, and the least imo on sniper/rifleman
2C4 or 4 slams ( rearming off opfor bunker ) will destroy it
Sandbags / razor can be blown up as well
Hold shovel when digging..
Thats about all the pointers I can think of that might of threw me for a loop at one time, hope it helps..
