Melee specialist

"No bot with an oversized back-scratcher is going to stop me!"

- The average Decepticon on encountering a melee specialist for the first time. When your entire battle strategy is to run directly at the guy with the big gun and try to hit him, you might consider becoming a melee specialist. At some point in the Great War, someone seems to have gotten the idea that recruits could be fast-tracked simply by giving them a really big stick and sending them out to fight the enemy. The result may not be fearsome on its own, but a group of them can bum rush an enemy and pose a significant threat.

Melee specialists were common during the Great War. Perhaps not so much afterwards.
