You cannot select a different weapon while moving.
You cannot order your team to take cover so they get shot.
Controls are dumb
ARMA2 is way better.
Peoeple are crying that it's too hard and that ARMA2's menu's are too complex. Come on! A military simulation should have tons of options and menus. In Arma2, you can order your squad to do whatever you want.
Lastly, OPF2 feels more like FarCry 2 than a sequel to Operation Flashpoint. Codemasters. Enough said.
