experimental
divided in 2 squads
2 heavy/medium soldiers + 1 heavy medic = assault/objective team ( these are the guys that push forward )
( may get additional 1 engineer while in need )
1 soldier + 1 light medic + 2 medium/heavy engineer = support team/defensive ( these are the guys who stay right behind the assault team covering them from getting flanked and giving them fire support and defend defensive position )
1 operative on his own/assault team. mostly attacking/distracting the enemy from behind/sides while the support and fire team keep the enemies suppressed. this is easier said then done ( to be realistic there will be at least 1 loner in the most of the teams either if you like it or not )
this would be a sweet setup for my type of gameplay
