A 'mixed fl;eet' is always a thorny one....... The moment something goes wrong that's not in the usual supply chain/Ordnance system, you. 're well and truly f...., er........., knackered. Think Unimogs in the Falklands or Bedfords captured at Dunkirk

It's like all these old fairy stories about someones friends, dads uncles mates patrol who threw their Brens/Stens away and used MG42's or MP40's. Yea....... They might have found and kept one, but they certainly didn't use it as the norm.
