"oh good, we got non-combatants in the facility." mike said signing in ASL for Anna. "that's going to make it a one sided firefight should the mission go tits-up"
he coughed again to clear his throat. "Mike Nawlin, or 'Lucky' as i've been called and prefer in the field" he spoke, . he had to put a bit of effort to resist signing "LUCKY" "FRIEND" ""DON'T SHOOT" or "POTATO" and remain professional. in all honesty the thought of a 7.62mm round through his occipital bone made him reign in his sarcasm more then goodwill. 
"worked as a fireman for a while, earned my paramedic, and then got snatched up by the U.N. due to my past work and experiences they trained me in rapid Infiltration and Extraction." he looked around at the group. "Meaning if someone gets cornered, I'll be one of the people fighting the way in. If we find ourselves surrounded, I'll try to find us a quick exit." he thought a bit. "think of me as a happy medium between crawling through air vents, and blowing holes in walls that alert everyone in a mile radius or more."
 he shrugged. "other then that, I can treat wounds, handle a rifle, and blend in just about as well as anyone else."
