JMA,

Amidst your post was:
Of concern to us was the fact that at one point operational intel was being passed on. For example on one camp attack into Zambia when we were going through the paperwork in their ops room we found a fresh signal they had received that morning saying "You will be attacked at 12h00 today".
I learnt when in Zimbabwe in 1985 that operational security lapses had caused immense concern and aside from the "usual suspects" some thought was given to the regular arrival of external supporters before each major external operation. Supporters who provided the funding and more - they were not identified, but the finger of suspicion pointed northwards to Arabia. Their arrival in executive jets invariably was to Salisbury and could have been monitored.

After 1980 the Rhodesians discovered that some of the lapses could be attributed to the weather station at Salisbury airport, which was all-African and from their position could monitor the build-up of aircraft. Maybe even requests for weather reports? IIRC the Rhodesian Air Force main operating base, New Sarum shared the civil Salisbury airfield.

Security did work and I was told that ZANLA had never worked out where the ammunition was stored for the AML armoured cars; it had been in the squash courts and had been unseen.
