Roughnecks

Bouncin' Killers
The Roughnecks are Discord's shock troopers. This branch of his army is composed entirely of kangaroo. When they first reappeared, they were using muskets, cannon, howitzers, and small hand-held cannons. Since The Great Alliance, Equestria began to supply them with more modern weapons.

Their tactics are effective, but involve certain death for anyone on the front line until the enemy is destroyed. They charge forward into the enemy, shooting and reloading on the way there. Once they make contact, they engage in melee combat, usually with blades.

Each kangaroo acknowledges that fact. In their philosophy, it is honorable to die in battle.
