To echo what some others have said, squads are going to be more of a on the fly type setup. When you spawn as reinforcements it might be good to take account of what classes are there then decide if you need to spread out into multiple 'squads' or stay as a cohesive unit.

My thought was to break into two teams upon start of the game, each team with an objective. Upon the first reinforcement wave, that group will backup whatever squad (from the beginning) lost the most men or needs more help. If their were equal casualties yet not enough to form two reinforcement groups then obviously other ideas will have to be hashed.

Here's some quick tips... I'm at work so these aren't fleshed out. Just quick thoughts.

a) Never move by yourself or run into the open without having someone to cover you. I will admit I'm extremely guilty of this in the beta because half the time I die and not around any TG guys. I'll high-tail it to their last known location ignoring any tactical movement. This is a recipe for a quick death. You should move as a unit (or at the least a group of 2 soldiers) taking the time to move from cover to cover. One bullet can spell your demise unlike BF2 where the chances of a one-hit death are slim. Yes, it's going to be slow moving, but you're more helpful to your team if you're alive.

b) Know your class and it's weapon capabilities. Don't lead ANYWHERE if you are a MG (it isn't a BF2 SAW). You can fire if your not deployed, but it's not easy and it's extremely inaccurate. SMG's (or automatic riflemen) should lead the way in CQB areas. Bolt action rifles simply don't cut it close areas. Bolt riflemen should stay near the back behind cover picking off players while SMG's move up. MG's should NEVER deploy by theirself. They need at least one rifleman with them. Panzerfaust has a max distance of about 100 meters. Practice with it offline and learn to gauge distances then use the site. It takes a while but it's worth it when you are taking out tanks that are constantly pinning you down. If you are a CO, know how to use the binocs to call in artillery and how to mark rally points on your map. Also know how many strikes you get per round, don't waste them as they can be invaluable. Soldiers should know where find all the radio tables to call in artillery marked by leading classes.

c) You move extremely slow with iron sights up but they can be your saving grace if you encounter an enemy who has to fire from his hip. Learn to lean around corners with IS up, not just walk around them in BF2. This is not BF2, no where even close. I can't stress that enough. This is more like Rainbow 6 with combined arms, multiple classes, and intra-map respawns. Also, you can 'crouch-run' by holding down both modifyer keys.

d) Grenades are deadly. Know where you are throwing them and for what reason. They are helpful concussive devices that can gain you the upperhand if you are trying to flush an enemy or may have to charge into an area. If you find one at your feet, run and hit the dirt. Fragmentation grenades stand a less chance of killing you if you are prone. If you are firing at an enemy fairly close and he ducks behind cover, chances are a grenade is coming your way. Have an exit planned.

e) Use your map! Radio and re-supply areas are marked on the map as well as requests for artillery strikes. The grid is easy to use and should be used to call out targets if you are calling them out to your whole team. If you are using local VOIP, a direction maybe easier. Your compass is at the bottom left of the corner, the direction at the top of it is the direction your facing. As with all engagements, state the number and distance of any targets.

f) Tanks should be supported by infantry on combined arms maps. They can provide great help in taking out panzerfaust, sapers, and ATR enemies. When engaging other tanks, never expose your front or side completely. I don't know the correct angle, but my rule of thumb is that the enemy tank should be between your 10 and 11 or your 1 and 2. Practice and know how to use the gun site on the tank, it's much more easier than guessing. But the ^ on your target and adjust the range using your Q and E keys.

g) You are going to be frustrated. You are going to want to quit. You may even hate the game, especially after playing BF2. Practice, be patient, and adapt. In addition, don't take any play that you've experience on the beta server to be the norm on the TG server.
