Millions of CONSCRIPTED soldiers of WW2 would have a word with you.
Let's just nominate the Folgore and the Ariete divisions (Italy, WW2, 2nd El-Alamein). The 62nd Army (USSR, WW2, Stalingrad). The 4e Division Cuirassée (France, WW2, Battle of France). The 101st Airborne Division (USA, WW2, Battle of the Bulge). The German U-boot fleet (Germany, WW2, Battle of the Atlantic).
