Sergeant Tyler Tallman, a rifleman and squad leader

Sergeant Tyler Tallman, a rifleman and squad leader with 3rd Battalion, 8th Marine Regiment, shakes the hand of a role playing host national at the completion of a pre-deployment certification exercise for Special-Purpose Marine Air-Ground Task Force Crisis Response-Africa on Marine Corps Base Camp Lejeune, N.C., June 19, 2015. For three days Marines with SPMAGTF-CR-AF took to the field to work with role players representing African host nationals and conducted situations they may encounter when deployed to various African countries. This exercise forced all the Marines out of their comfort zones and gave them practical and life-like scenarios in preparation for their upcoming deployment. (U.S. Marine Corps photo by Cpl.
