Making use of armor-piercing rounds, it might beat 192mm of armor at 914 meters, enough to pose sufficient danger to virtually any German armor of this time. Manufacturing started in 1944, and Archers had been sent to the British Army's Armoured and Infantry Divisions, who started utilizing it from October.
