Slipping a few of these guys in a huge horde would be a big surprise to those armored vehicles who think they can just plow through the horde to no harm to themselves. The only problem I see with them is if they are being deployed in the underground mazes of Gibraltar it might not be the best idea to have large explosives down there unless they are used purposely to seal up tunnels to keep the enemy from advancing.
I'll be adding these bad boy to my horde for sure!
