Their job is to get across the red zone (from back lines into front lines, while in range of enemy fire) as fast as possible. If Russkies try that in any vehicle larger than a quad-bike ATV they will instantly get drone-dropped or mortared to oblivion. So you can't send lots of people on one vehicle.
But if you send them one by one, they don't have nearly as much carrying capacity for ammo, explosives and mines. one man can only carry so much.
So you get some e-scoots and duct tape/clingwrap that gear onto it. And send them once by one, hoping that at least a couple of them could get through.
