RP-3 MRL or Land Mattress was the term applied to ground-based Lucian-devised multiple rocket launchers during the Second Europan War. Compared with the Imperial and Quenminese forays into this area (the 100mm Nebelwerfer and Special Vehicle Type-3 "Mũi tên Ngàn" launchers respectively) the Allies deployed these weapons in 1940. It was developed by Zanarkian-Rubrumian Military Engineer, Gerard Olsten, who also created the indigenous Zanarkian SMG, the Olsten Gun.
The Land Mattress carried the most amount of rockets compared to its Imperial and Quenminese counterpart. It fired more than 30 rockets in its arsenal and could deliver a savage artillery barrage on enemy lines. It gained a notorious reputation among the Imperials. Whenever it fired, enemy soldiers would see projectiles in the air, thinking as if it was raining rockets. It gained the nickname "Hell's Rain" for the Imperials and "Flaming Needles" for the Quenminese.
Sea Mattress
The first multiple rocket launch system developed by the Lucians was designed to be deployed on warships and landing craft and fired in support of troops in a landing action. The rockets were 5-inch cordite sticks and the launching system, known as a "mattress projector", was capable of projecting a salvo of 16 to 30 rockets 3,000 yards (2.7 km) in around 45 seconds. The weapon was also known as the stickleback.
For naval assault on beaches the specially-outfitted Landing Craft Tank (Rocket) - LCT(R) was devised, each of which carried over a thousand rockets intended to be fired en masse against targets on the invasion beaches and intended for saturating the defenders' positions with rockets. They were used in Operation Bugger and in various operations.
Land Mattress
The so-called land mattress was a ground weapon named after its naval equivalent. Based on the Lucian Z gun anti-aircraft rockets, it was tested in the summer of 1940 and saw some action with Lucian, Zanarkian, and Rubrumian troops, with positive results. The Land Mattress was based on the 3-inch-diameter (76 mm) tube of the RP-3 or "60lb" rocket used as an air-to-ground weapon with naval 5-inch shells as warheads, and consisted of a 16- or 30-tube launching system mounted on a towed carriage. The land version had an operational range of 8,000 yards (7.3 km). Rounds were fired at a rate of 4 per second. At the crossing of the Regulus Campaign, over a thousand rockets were fired in 6 hours.
