Tunnel Rat was a tough kid that grew up on the streets in Brooklyn, got in a lot of fights, that sort of thing. His father had a drinking problem and was violent towards his mom and to him and his siblings.
He joined Joe and decided upon explosive removal, as a symbolic way to diffuse the bombs he never was able to with his father in his childhood.
I love Tunnel Rat but I don't know, just would of maybe liked to have seen a different version of legs/boots, this version works as more of a jungle version.
