Though, even if accidentally, this helps with emissions (AFAIK, DoD vehicles don't tend to be subject to same emissions standards as us mere mortals), that would be a win, too.
This is stupid and if the Army is really doing this it's a reflection of complete sophistry.
Besides, it makes sense to not depend on resources controlled by your enemy.
Anyway, last month the Swedish truck maker Scania tested an electric vehicle in -29C (-20F), making your initial point irrelevant.
At some point in a struggle for command (war), you need boots on the ground. Until then, yes, it will probably be all airbased.
