for military bases to use.

My dad used to work on a military base as a civilian in wastewater treatment plant. Part of his job, about once a day he'd hop in their little public works pickup truck and collect some water samples from a handful of places around the base, check on some gauges at a couple different sites, etc. If I had to guess he logged probably a max of 5 miles on a busy day (and that's probably a very high estimate) All low speed, pretty sure speed limit around most of the base was like 25mph. He could practically have done his rounds in a power wheels Barbie jeep (and really the little Chevy S10 or whatever they had was probably overkill for their needs, something like a golf cart or kei truck would probably have been plenty)

And except for that maybe hour out of his day he would drive it around, that truck would pretty much just sit.

That would be such an ideal niche for an EV, it's got like 23 hours to do nothing but charge. Hell, you could probably even charge it off a solar panel, doesn't take a whole lot of juice to go 5 miles.
