When respawning as insurgency against AI, I've noticed that often the security AI are already in the spawn area. You can't defend yourself as the reloading animation means you can't fire, and you can die pretty much instantly.
At times when under mortar/artillery/rocket/gunship/vehicle MG etc attack, despite taking cover inside a building and staying away from windows and doors, you can still get killed. If this happened rarely then OK, but it's very frequent, and annoying.
But great job!
