The standard handheld artillery of the pre-war British Empire armed forces in 2077, used for accuracy rather then speed compared to its American counterpart; the Grenade Machinegun.
Sent for distribution in 2056 then finalised in 2057, the Grenade Auto-Cannon was given commendations by grenadiers and artillery masters for its superior accuracy and overall damage compared to the older Grenade Machinegun; commonly referred to as the "Powder Spitter". After many years of service the model was updated for use in the Scandinavian-Russian war, new targetting parameters and a snapshot camera feed were added to the onboard computer for fighting in extreme weather along with an arctic camoflauge, added to the ammuntion drum and front facing blast shield. The new Auto-Cannon Valkyrie Pattern entered service in 2074 quickly decimating the Russian Tanks leaving other weapons, such as the British Empire Tri-beam Prototype, to finish off the infantry without coming under direct heavy fire.
- The Valkyrie Pattern of Auto-Cannons featured updated onboard computers which took a stream constant pictures of the battlefield, took the range of the enemy, then altered the firing force accordingly.
- This specific Auto-Cannon was from the 271st Royal Infantry division, as shown on its hull.
