Even civilian e-motorcycles can hit some crazy distances these days, I have seen a few with 100-150 miles of range. If the military wanted to they could make their own with double or triple the amount of batteries, it will just behave more like a full size motorcycle than a dirt bike.

I imagine it will be awhile before they switch to fully electric trucks. I could see a hybrid being used though it could possibly increase maintenance challenges.

Non-flammable batteries would be a HUGE leap forward for the military, they could have fully electric drivetrains with no risk of fire, would be amazing for tanks. The batteries could even form a part of the internal armor, wrap it around the ammo rack etc.
