Commando Comic #785: 'Let Battle Commence!' (1973)
 
How do you win a battle? It's easy. You start with an ancient paddle-driven tugboat and you steam out into the open sea. You have only some rifles on board but a few days later you capture a Japanese torpedo boat. Then you join an enemy convoy and sink a troopship! Yes, it's that easy...as long as you've a will of iron, nerves of steel, and the sort of courage that heroes are made of.
