Yes, I'm ex EOD...Am I correct in saying this was used with the .50 cal de armer and rocket wrench?
It was used with the .50 de-armer. 1989 was the first year I saw it although it would most likely have been trialled before then - perhaps at the Army School of Ammunition or by LSA 2a. The cartridges were still marked Experimental in 1989.
