Cpl Mason Neff and his dog Bingo were in an area reputed to have a high concentration of improvised explosive devices when Bingo began acting agitated. Neff’s fellow Marines said it appeared that Bingo was trying to prevent his handler from approaching an IED when the device detonated, killing Bingo and critically injuring the soldier.
