Here is the formation i would like you guys to follow tommorow

Berkut/Niner/Breaker or Operation SlingShot

the reason i call this formation slingshot is this

Berkut : Secure Points/OutFlanker
2 Support/2 Assault
1 Engineer
1 Recon

Berkut task is to make sure No Tanks or Enemy can flank us without we are knowing about it
When at flag position,Berkut will make sure no enemy can ambush from behind

Niner = Frontier/Ambush(Flanking)
1 Support
2 Assault
1 Engineer/1 Recon

Niner task is to push the safezone infront enough to make Berkut/Breaker to move foward and secure safezone(in middle of between the flags perhaps)

When they are ambushing,they will supress the enemy until breaker comes in
so expect tight positioning between squadmembers

Breaker = Secure Points and Supressing
2 Support
2 Assault

Breaker task is to make sure that enemy break their formation by laying out supressing fire at both corners of the streets/ground
Assault class in this squad will be to keep the supressing fire alive no matter what
As you can see
Breaker and Berkut will make sure the area is secure then launch Niner ahead to hit the enemy continuously

Tips for each squad formation

Berkut = Recon need to learn where to deploy spawn points and safely spot the enemy ahead by using any mean nessary(MAV/EOD/TUGS/Softlam)
Engineer need to be ready to lay mines for incoming enemy heavy armor or destroying enemy using JAV/RPG
Support/Assault Class will need to make sure no one outflank recon/engineer until zone is declare safe
Niner = Support must learn how to rapid suppress and take cover
while Assault class need to make sure enemy is down before moving up

if pick recon = learn how to deploy MAV for spotting a.s.a.p and take cover
if pick engineer = learn how to destroy enemy vehicle in unexpected situation

Breaker = Lay down as much supressing fire and take down enemy that is advancing
of course in some situation to take out enemy mortar if detected(since you guys are from behind)
