On my way to FI in 1983, I was kitted out at Innsworth with KD at HM expense [on loan]. This vital addition to my travelling wardrobe of ever-increasing weight was to enable me to be properly dressed during my transit through ASI.
Having been disgorged from the VC-10 [wearing DPM/green kit, IIRC], I actually spent about 30 minutes at ASI before being led onto an RN helicopter and air-delivered to the SS Uganda [anchored off-shore]. There I spent 2-3 days bobbing around 'on the hook' whilst loading of personnel and stores was completed, immaculate-ish in my KD. When we eventually sailed, it was straight into DPM/green once more, and the KD was never seen again until returned to Stores some months later.
I always thought the RAF might just have gone a wee bit OTT on this one.
