Ni = Death Star: Slow to act, but deliberate and annihilates everything in its path. Likely to be thwarted by the tiniest overlooked sensory detail like an exposed exhaust plort.
Ne = Dreadnought: "Aims" here, there, and everywhere. Many will be caught in its wide field of fire, but such targets are only damaged before its guns move on to something else.
Se = X-Wing: Fires on the move, unlikely to be pinned down, but not the hardest hitter unless opportunity arises from a combination of both luck and skill.
Si = Like a Bantha!!!: Traditional, slow-moving, and often obsolete, but reliable and a decent vehicle for keeping lofty-headed sky walkers grounded in the sand.
