| Notes | The Boys was the standard infantry anti-tank weapon used during the early phase of the war. It was heavy plus had a strong recoil and even at very short ranges it could only penetrate at most around 20mm of armour. It was issued at company level until replaced by the more effect PIAT. It continued in service mainly behind the front line and was also mounted on early armoured vehicles. |
