Starship Troopers: The KMC Version

The "Starship Troopers" bugs are all about to invade Earth. It is up to you(Yeah, they're getting pretty desperate) to form a team of up to twenty people who can wipe out all the bugs.

Rules:

1. Try to make your team be the weakest team it can possibly be while still being able to wipe out the bugs.
2. Try to make the team as small as possible.

Weakest team? Small as possible? Are you stoned?

Read the rules; Armies (from established films) are allowed. Other than that, the rule is 3 vs. 3 as to avoid confusion.
