The Boys anti-tank rifle was suitable for sniping, as well

During the assault on Bardia, in January 1941, two Australians, Privates Kneen and Hurley, traded shots with an Italian anti-tank gun, and succeeded in defeating it. This was just south of the road to Tobruk on the outer edge of the defense perimeter surrounding Bardia. A platoon from the 2/1 battalion had attacked at 9 in the morning and was beaten back by MG fire and pinned down. Once the anti-tank gun was silenced, the original attackers were able to withdraw. A fresh, battalion-sized attack was mounted in the afternoon, and post 54, the well-defended position, was taken. One third of the defending 30 men were casualties. This goes to show that the Italians could fight bravely and effectively. This is based on a section in Gavin Long's book To Benghazi.
