>>13357023An assload of martial and military weapons, a good amount of electromagnetic frequency understanding, programming, radio communications, physics, chemistry, biology, logistics, math, animal controlling techniques, speech and language, LOTS of weapons.
Bonus: Access to nukes, access to a space armada, and of course, the duh obvious ability to wage war. Anything that gives you rapid understanding, or things to give rapid comparisons, or edge, over an unknown, possibly hostile enemy.
