Have you come across Greg Stoker, US vet? He explains the strategy the Gazans are using. Basically, they are sniping all the higher ranked officers leaving the poorly trained lower ranks causing morale issues.. And he says the higher ranked officers are in the frontlines because the regulars don’t know how to resolve some of their tactical issues, they simply don’t have the training.
He also makes an interesting comparison with the battle for Stalingrad. The Germans had bombed it to rubble but then had problems manoeuvring their tanks and other heavy vehicles. Russian snipers picked off higher ranked officers.
