Team 4 from the 321 Special Tactics Squadron pull a Humvee during Monster Mash Sept. 26, 2014, on RAF Mildenhall, England. The Monster Mash consisted of various events such as carrying a Zodiac inflatable boat, marching with a 40-pound rucksack and a blind weapons assembly. A Monster Mash is a long-standing special tactics tradition which combines events designed to test the strength, stamina, and problem solving skills. (U.S. Air Force photo/Tech. Sgt.
