Don’t start a gunfight from a standstill unless you’re sniping. You're much harder to hit while you’re moving.
Always avoid starting a push across open terrain, cover is essential to protect you from flanking and other enemy squads.
Use your squad's abilities to find higher positions with a good line of sight to an enemy squad before starting an engagement.
If your squad is exposed during a gunfight don’t hesitate to disengage to find a stronger position.
Use grenades and area denial abilities to control the movement of enemy squads and deny the use of cover. Force your opponents to choose between eating a grenade or surrender their positioning.
