The approved chemicals used for ground maintenance are ROUNDUP, GARALON, and occasionally ASULOX.
During exercises to train troops for defence against chemical warfare, white smoke, CS Gas (Orthoclorobenzlidenmalononitrile), Chemical Agent Training Mixture Polyethyleneglycol 300, and Amyl Acetate are used, the latter to prove respirators prior to use.
The Nuclear Biological and Chemical Battle Run, the area of Sennybridge Training Area used for training in chemical defence, was used by 3 Commando Brigade, the Royal Marines for training on 2, 3, 4, 5 and 8 September 1998. The remainder of the training centre was used for a number of infantry patrolling, live firing, and other tactical training exercises over the period in question.
