I would put plows on the front of all tanks and simply bury them alive.
Hamas is evil and barbaric but they are not stupid, supposedly their attack to 2 years to plan, they are smart, the tunnel system is extensive and probably covers the entire Gaza Strip, with multiple openings and supply depots with rockets and mortar rounds stored up so as they withdraw, they constantly have ammunition to shoot.
The openings have to be found, I’m sure no signs are out pointing to tunnel openings, it’s hard dangerous work and takes a lot of time.
