Don't they always clam that, it's more about defending if it should hit the press officers are buying their own kit. MOD spring to mind, and the army kit, lad buying there own kit.
When I worked for The AA, they supplied a tool kit, and said the same this is all you need, there was their world and the real world.
I think you'll find there isn't too much of a problem with squaddies etc buying their own kit. PPE, for both MOD and the Police, of course has to be issued. But things like bought kit, clothing, boots etc are all acceptable as long as they do the job and are suitable. It is common to see non issue smocks, webbing, backpacks, boots, survival kit etc amongst infantry troops.
