Going prone (default C) will help conceal you from enemies, providing a increase to accuracy and increasing concealment while reducing the chances of being hit.
Take full advantage of cover.
Suppression fire can overwhelm hostile targets.
Going prone or crouching affects detection range and hostile reaction time.
Being in the prone position has a higher concealment rating that crouch but with less mobility.
Distance between your soldier and hostile also affects reaction time of AI enemy.
Shooting a non-silenced weapon causes you to be immediately detected if you are in detection range of enemy.
All AI hostiles have a interval between attacks, if you are not in cover but behind wall, use their interval to get a timing to attack.
Behind most cover, your head is still vulnerable. In trenches, you are usually completely hidden by walls.
The perfect position is on a hill (or building), with cover surrounding you, except for a narrow twenty degree arc of fire.
Flank the enemy, try to move to positions which are perpendicular to the enemy's current cover.
Use the high ground, height gives you much greater range and visibility. Sometimes you can shoot over lower cover. With a grenade launcher and a four story building, you can rule the entire visible area with low vulnerability.
Have a planned fallback position, if you are getting overwhelmed, retreat!
