Once flew washing machine, dishwasher, fridge, freezer out to Cyprus for a friend. Saved them buying new stuff, saved the MOD from paying storage fees etc etc.
Later one on our sqn had his stuff flown home on retirement. He then joined Cyprus Airways and asked boss if he could fly the stuff back - boss refused - but his mates flew it back anyway even with a bike strapped on the pannier.
While there was a marginal cost to the MOD the guy had given them 20 years and as a tax payer owned a bit of it anyway.
