VSOs can be embarrassed whether serving or retired, if retired having fingers pointed at them by giggling ROs in their clubs and if serving quiet guffaws in the Mess as they pass by .
Disposing of eqpt & selling off the spares (or gifting them) makes perfect sense, and not only to the bean counters, which is why we've done it many times. If eqpt are not part of the Land Eqpt plan then they cost a fortune to store & maintain (Sheds, manpower, spares, lubricants, fuel, deterioration etc etc etc) and spares that can only be fitted to obsolecent eqpt take up the limited & valuable storage space we have left. To continue to use obsolescent eqpt as you suggest costs a huge amount from the repair budget, you'd spend much less on new replacement eqpt and of course the obsolescent eqpt becomes less and less effective the longer it is kept in service, if you can keep it going that is!
As an aside, I lead a team inspecting & conditioning all major assys returned post GW1. During that project the depot ran teams disposing of things like desert boots that were no longer in service (left boots one week, right boots the next, seriously and no thought of selling them to the mil wear shops) and a huge amount of the green combats that had gone out of service before I joined in 1975! There comes a time when stores are for storing becomes absolutely stupid and nowadays every action has a price tag on it.
It’s says stores on the door, not issues
