Rules of engagement:

1. If it moves, shoot it.
2. If it doesn't move, poke it with your turret and then shoot it.
3. When in doubt -- Shoot It.!!
4. Overkill works.
5. Just because it breathes doesn't mean it should.
6. If all is going well its a ambush.
7. If it's not moving shoot it anyway, it might move later
8. If it starts moving, Jam it, shoot it and call for back-up.
9. If all else fails - get revenge

There is no "overkill". There is only a disproportionate appliance of force.
