So, A and B are countries at war. A recruit’s citizens from C,D,E and F to go fight for them. As a citizen of those countries, I’d like to know what the mix of soldiers at the front is. I’ll bet there are three or four C,D,E and F’s to every A getting shot at.
Russia’s tactics appear to be, sacrifice the men to force the enemy to give up their locations by firing and then force the enemy to use up his ammo. It’s the opposite of what a general should do. But if you don’t value your men, then you can spend them like a drunken sailor spends his money. If you had one specific target that gave you some inordinate advantage, then perform the sacrifice knowing in the end the overall total will be lower. But the Russians are using this tactic to take everything from the low ground to garbage heaps.
Those that get captured should be offered asylum. Pretend they died and send back ant personal items for ‘proof’.
