Sgt Mack Valentine
Sgt Valentine is not only a assault specialist, but is also a demolitions expert. Originally trained as a marine, Valentine moved to the Green Berets in 2003 in order to be part of the rapid deployment into Afghanistan. This put Valentine in a position in order to exercise his training on true targets.
The Afghanistan campaign provided Valentine with some great experience, and he again transferred to Iraq once the invasion there began. Somewhat disappointed with the resistance he found there, was later wounded when a IED he was trying to disarm was detonated.
While he was recovering in a hospital in Germany, Valentine was approached by the Section 20 group. Knowing that he would only be deployed into obvious hotspot areas he jumped at the opportunity.
