7 If the food is good enough the grunts will stop complaining about the incoming fire
8 Mockery and derision have their place. Usually, it's on the far side of the airlock
9 Never turn your back on an enemy
10 Sometimes the only way out is through... through the hull
11 Everything is air-droppable at least once
