The Intelligence Corps of the British Army is very sneaky Beaky. In N ireland were very active. they have elements who are very under cover and it´s all kept quite. this is what makes them very Dangerous. Remember Meeting one who was Intelligence Corps or SAS i don´t know, came up to me showed his ID and wanted to enter camp. Had a beard and looked like a tramp. We had next to us very high Ranking Staff Officers so it was known that there were Undercover operations going on. Guy just walked up and smiled and said, allright mate... i knew straight away but had to send him into the Guard room. The Duty Guard commander just came out winked at me and said he´s OK. Said it all.
