Photo B0084: Military Policemen of the 720th MP Battalion underwent testing of a new and improved British Tear Gas during riot control training on Fort Hood, Texas sometime in mid-December 1960. “Man this is powerful stuff,” CPL Robert G. Morrison bending over, center, is saying to LT Benjamin Caster who is helping him hold his rifle. CPL Morrison had just received his first contact with the new gas. CPT’s Roy K. Williams and Robert K. Udclaire (S-3), right, stand by to assist of things get worse. If you can provide the companies of these MPs use this Email Link.
