First, who is Sgt Rock and Roll. Fair question as it is not as mainstream compared to say, Duke, Snake Eyes, Destro, or Storm Shadow.
Dubbed as Machine Gunner, his real name is Craig S. McConnel, and his rank is that of Sergeant E-5 (later promoted to Staff Sergeant E-6). Rock 'n Roll was born in Malibu, California. This is according to his Wikepedia page.
This toy that I have was originally released in 2008. I got mine, ten years after via seller from Facebook. Not carded but the condition of the figure is very well tight.
My interest in getting this figure, despite it's being relative unknown is my friend used to have this figure back then. Yeah, it's that shallow.
At any rate, the 2008 iteration of the figure, just like most of its cousins is top notched. Great attention to details, pose ability, minimal but practical accessories or weaponry, highlighted by its MACHINE GUN and AMMU.
I am not sure if this figure is inspired by Chuck Norris. But it is totally bad ass.
