Len Moore fought with the 2nd Battalion Kings Royal Rifle Corps 2/KRRC across the deserts of North Africa during WW1 from 1941 to 1943. They were equipped with the .55 inch Boys anti-tank rifle and 2pdr Anti-tank guns. This was later upgraded to a 6pdr Anti-tank gun.

The Boys .55 inch Anti-tank rifle

A bolt action rifle fed from a five-shot magazine, the weapon was large and heavy with a bipod at the front and a separate grip below the padded butt.[4] In order to combat the recoil caused by the large 0.55 inch (13.9 mm) round, the barrel was mounted on a slide, and a shock absorber was fitted to the bipod along with a muzzle brake on the barrel. The Boys rifle was used in the early stages of World War II against lightly armoured German tanks and combat vehicles. such as the Panzer I, Panzer II and early models of Panzer III, increases in vehicle armour during the Second World War left the Boys largely ineffectual as an anti-tank weapon.

British 2pdr Anti-tank gun

As German tank design evolved, anti-armour performance of the 2-pdr gradually became insufficient; however, the gun owes a large part of the bad reputation it gained during the campaign to the open terrain, which made the high-silhouette piece hard to conceal, and to poor tactics. The guns were never equipped with High Explosive rounds, which would have given the gun some capability against un-armoured targets. For most of the North African Campaign, the British army had to rely on the 2-pdr, aided by the 25 pounder gun-howitzer functioning as an anti-tank gun—a role for which it was capable, though at the expense of taking it away from its main artillery role.

British 6pdr Anti-tank gun

The 6pdr gun replaced many of the outdated 2pdr guns issued to units of the Kings Royal Rifle Corps in 1941. The 6pdr gun was a 57 mm gun. It made an immediate impact on the battlefield as it was able to penetrate any enemy tank then in service. In the most celebrated action, the 6-pounder guns of 2nd Battalion, The Rifle Brigade (together with part of 239 Anti-Tank Battery Royal Artillery under command), destroyed more than 15 enemy tanks in the action at 'Snipe' during the Second Battle of El Alamein. When the German Army introduced the Panther and Tiger tanks to the Battle field the 6pdr gun became obsolete over night.
