Correct...logs will not stop a shape charge.
I don’t mean to be contrary but I am not talking about shaped charges or artillery or maverick missles I am talking about the plethora of videos of vehicles of all types being taken out with grenades dropped down hatches and mortars dropped from drones. Logs would have stopped the damage as noted in the drone video that showed a mortar or grenade dropped down an open hatch(pro tip close the hatches war has changed) and the vehicle catches on fire the vehicle right behind it has of course open hatches but three pieces of ordnance are dropped on it all miss the open hatches and basically no damage to the vehicle. Lol I know this is perhaps a pet pive of mine but the first vehicle burned up because the ordinance went through and open hatch. A closed hatch a pice of plywood or logs would have stopped that. Lol last post on this will drop it :)
