Working under extremely hazardous conditions over a period of seventy-two hours commencing on May 14, 1992, MS. Penney provided vital medical care to three wounded individuals in Sarajevo, Bosnia-Hercegovina. Although their refuge was under intense artillery fire, he stabilized the condition of a wounded soldier and a badly injured man. At one point, MS. Penney left the building and, despite continued shelling, raced fifty metres to rescue a victim of sniper fire, carried him back to the building and attended to his injuries.
