Utterly Mad

(going to assume Abraham went to the wall as well)
You all start towards the wall with the militia leader close behind. The militia leader looked at Pratchett and said "Yeah, well this is the first time they brought fucking mortars to shoot at us. Looks like half my boys are just blood and guts at the bottom of some craters now."
The three of you see and hear a couple more explosions before reaching the wall. You hear one of the militia men shout "Where did these idiots get grappling hooks?"
As you take cover you see one of them hop over the wall and drive the head of a hand axe through the one of the militiamen's skulls and shout "I'M GONNA KILL ALL OF YOU FUCKERS!"
You can also see two gunman in half cover, one behind a pile of wooden crates and the other behind a small stack of concrete mix bags below you, two gunman climbing the wall, and the Berzerker standing over the body of a now deceased militiaman. The three of you react quickly and are able to take aim at your targets.
