[SecUnit does a quick search in its memory archives for 'fusion cells', comes up with a lot of contradictory information, some of which suggests that it should be evacuating the area by at least a few dozen kilometers. So it abandons that search. It would probably need to spend a full day doing research, and it doesn't have access to the full digital library, just a whole lot of dubiously accurate entertainment media.]

We haven't come across any fusion cells that I know of.

[Grudgingly answered, because it supposes weapons access is a key point that should be addressed.]

Current means of recharging include ad-hoc hookups to vehicles and the Convoy. External power sources can't reliably be found, especially if the Convoy leaves previously populated zones behind.
