Yeah, I heard that one recently too, that all military vehicles will be "environmentally friendly". Totally implausible to anyone that's spent five minutes in the military. Biden's only experience with the military is vicariously through Beau Biden, a LAWYER in the DELAWARE NATIONAL GUARD.
I mean honestly, what will they do - fight and maneuver for 8 hours and then have to plug in for eight hours? Will they have to take windmills and solar panels to the front lines with them or will they abandon all pretenses of being green and just run diesel powered generators?
Point is, it's great for Joe to make a feel-good executive order, but the technology isn't there yet. Biden is putting our troops and our nation in danger to pander to the far left.
