I mentioned Jeremy Moore's IWM aural history which is good.
An even more insightful one is Julian Thompon's.
Whinging Tinny,
Thanks for the pointer to Thompson's recordings. Absolutely fascinating stuff - his complete RM history with lots of insights into campaigns that he was involved in prior to the Falklands - Cyprus, Aden, Borneo, Hong Kong, Northern Ireland, etc. as well as comments about his various staff and training postings.
I'm binge listening! I'm about half-way through (~15 hours!) and am now hearing his reminiscences about his time in Bandit Country in South Armagh. I particularly liked his anecdote about his marines who were tasked to patrol the railway. They were known as "the Railway Children"!

If you scroll down the page, you will see an unformatted summary of the contents of each tape. The Northern Ireland section begins at Reel 30 and the Falklands at Reel 40.
The tapes are unedited and there is a good deal of unexplained military jargon, so brush up on your TLAs.
