I like this. Good tactics, and the presentation isn't so bad either. Sometimes reloading doesn't work, I assume because the unit is out of clips, but the whole mechanic is rather pointless. Ammo isn't really a problem, just switch to the other gun (as a free action) or pick up a gun, so I suggest you remove the ammo mechanic altogether. Less confusion. Enemy respawning was a bit jarring. I had an enemy spawn in and knife one of my guys. This isn't actually a major problem, as long as the player treats the enemy spawn as dangerous, but you could force units to spawn at least a certain distance from their foes.
