takes practice... the more you play the more of the map you learn, the better your shooting gets, and the better the gameplay gets...

Just remember, no one should EVER die alone... if your not working as part of a team over teamspeak (which hopefully on TG you are) at the bare minimum, when you spawn in and see someone going off on there own, follow and support them... usually they will run into contact then you can assist in the engagement, or maybe even flank who's he's engaging if it's a long drawn out battle...

If your partner goes down in front of you with just a single shot or burst, for god sake, don't go out there also... it's an ambush or a sniper, disengage that area and flank it, come from a different location.

Remember humans are predictable, if they think they got a good location, or there getting alot of kills going in a certain area, or you keep getting yourself shot in the same area, either come a different way and ambush the ambusher, or at least change your pattern or direction often.

One thing I like to do when on defense is to start the round close to an objective, so the assaulter's come in close before the engagement, next time they thing I'm in the same area, but then I move further away from the objective, closer to there direction, if there guard is down because they think your closer to the objective, you got a good surprise, but then mix it up, don't you become predictable.

I also like my team to have further out engagements, where they can go out, get some kill time, report on the directions of enemies, then after a few minutes of contact, call everyone back to a last line of defense protecting the objective.

Remember your role both with your weapon and as a leader or follower, also remember the mission...

and good luck.
