Look back to WWII....the Russians sent Infantry Troops into battle that had no Rifles.....who had to pick them up from the ground from those how had been killed or wounded.....and urged them along into advancing by placing machine-guns behind them to prevent any straggling or retreat.
All they need to do is cloth them...transport them to the front lines and force send them forward to fight or die.
Life can be awfully cheap at times.
Does Putin and his Regime have the power and Will . to do that in the current War in Ukraine?
