'3 Commando Brigade RM'
The RM Commandos did not escape the cutbacks being reduced from eight units down to three. 3 Commando Brigade was reformed as 3 Commando Brigade, Royal Marines.
In 1947 the Brigade consisted of 40 Commando ( formed from the disbanded 44RM Commando), 42 Commando, and 45 Commando, and a Commando Engineer troop.
