One of the most important things for squadleaders to do is to talk a lot. Some people have difficulties to think of something to say so here is a little list of what you can say:

- spotting: ie incoming tank from the east, chopper incoming
- saying an asset is available
- attack plans ie: lets attack from the north, sniper find a place on high ground move in when he is in position.
- defence plans ie: c4 the flag, someone get on high ground to spot enemies.
- kit layout
- welcoming new players
- tell them what the job is (instead of using the markers)
- tell them they are doing a good job

One thing Im experimenting now is to come up with little attacking and defencive strategies and write them down before I play. It can be very simple like in the previous examples but it makes gameplay much better.
I think even the more experience squadleaders right now often just move in a flag without any plan, they just move in right to the front of the defence. Working out standerd plans in advance should help.
