Bolt Action - Commando Vickers MMG team
Whilst the Commandoes did a lot of raiding and slitting of German sentry’s throats in WW2, they also fought in epic pitched battles requiring some proper heavy kit to make Jerry and his henchmen keep his head down!
This then is the Vickers machine gun. Given enough belts of 303 ammo and enough water to cool its barrel, this reliable gun would fire indefinitely. It is served by 3 crew.
