I watched a video of some ukraine soldiers makeing use of what others commented on as a "shoot and scoot" (hit and run), or "kiteing" in gamer terms.
They would lay low, make use of drones to get a birds eye view, get coordinates (lazers? gps?), run in a small team of 4-5 people, carrying parts of a "reuseable laucher", deploy it (its like a little stand, that then gets 4-5 parts added ontop, and loaded with a rocket), and basically as soon as it was fired, they where pulling it apart, carrying their parts (each guy takes care of their part) and then running off, even before the missle even lands (and usually hits).
Apparently, these guys just keep doing things like this, you can hear frustrated russian soldiers fireing at them (their out of range usually) and theres like bush/vegitation in the way (sight issue).
I thought, damn... now I know why the russians are makeing such heavy losses.
These small hit and run teams (with drones, and smart weaponry), and the Guerrilla warfare they make use of, are apparently hard to deal with.... if your soldiers are basically just cannon fodder, just drafted, that are clumped up together in a caravan or such.
