QF 18-pounder Gun

The Ordnance QF 18 pounder was an 84mm (3.3in) field gun used by the British, Canadian, and Australian forces during World War I. Introduced in 1903, it saw combat action since the first year of the war, being used at the battles of Mons, First Marne, Le Cateau, etc. At the beginning it was used in the forward position, in the open field, as an enemy infantry killer, in the direct fire role; however, when the German began attacking and destroying the 18-pounders and their crews by the thousands, using howitzers that shot high explosive shells from hidden positions, the English changed their tactics, putting their field guns back, also in hidden positions, replacing the shrapnell shells for high explosive ones that exploded upon contact. But it never was quite as effective, as the German howitzers, against trenches and bunkers, for it had a flat trajectory.

Named after the shell it fired, which weighed 18 pounds, the QF 18 pounder had an effective range of 8.5 km and a muzzle velocity of 492 m/s. It was fitted with a screw breech and a hydro-pneumatic recoil system, and had a rate of fire of 20 rounds per minute. The gun was towed by horses and was operated by a crew of 6 men.
