Changing the original post, I’ve come up with the idea of creating a rocket branch for TT in trucks.
Russia: The Katyusha multiple rocket launchers (often called the “Stalin Organs”) were a series of rocket artillery systems deployed by the Soviet Union during World War II. They were revered by the Red Army and feared by the Axis powers due to their low cost, high mobility, and devastating firepower, they explained a bit for add them here recently
Axis : I think in the 8 cm Raketen-Vielfachwerfer could suit, The Soviet BM-8 Katyusha multiple rocket launchers used during Operation Barbarossa made a great impression on the German invaders. Proposals were quickly made to copy the captured Katyushas, but there was no industrial capacity available for new projects. There was also little enthusiasm for the project, because the German Army (Heer) already had production contracts for spin-stabilized rocket systems, such as the Nebelwerfer.
The launcher consisted of two parallel rows of perforated steel rails, onto which the rockets were mounted. The rails could be loaded with either German or captured Soviet rockets.
The rails were mounted on steel tube frames atop a variety of vehicles. Two of the most common were a Somua MCG half-track or an SdKfz 4 half-track and here they are the specs:
- Caliber: 78 mm (3.1 inches)
- Weight (Loaded): 6,853 kg (15,108 lbs)
- Projectile Weight: 6.9 kg (15 lbs)
- Muzzle Velocity: 290 m/s (950 ft/s)
- Maximum Range: 5.3 km (3.3 miles)
- Elevation: 0° to +37°
- Traverse: 360°
- Crew: 6

Americans: I won’t lie, I don’t know a lot about their rocket trucks, but I found one who could be interesting, the International M-2-4 1-ton trucks modified to fire 4.5-inch rockets

here the specs:
- Manufacturer: International Harvester
- Payload Capacity: 1-ton (2,000 lbs)
- Drive: 4-wheel drive (4x4)
- Engine: 233 cubic-inch (3.8L) “Red Diamond” 6-cylinder gasoline engine, producing 93 hp
- Transmission: 4-speed manual with 2-speed transfer case
- Dimensions: 198 inches long × 85 inches wide × 65 inches high (5.02 m × 2.16 m × 1.65 m)
- Tires: 9.00-16
- Launcher Designation: Mark 7 (T45) Launcher
- Armament: Navy 4.5-inch fin-stabilized rockets
- Launcher Layout: Mounted in the truck bed, the launcher featured dual magazines (right-hand firing and left-hand feed)
- Weight: 157 lbs per launcher
- Traverse/Elevation: Capable of elevating up to 35 degrees
- Tactical Drawback: The massive smoke and dust signature immediately following a barrage served as a perfect aiming point for enemy mortars and artillery. [1, 2]
Japan: The Experimental MLRS “Shisei 15.cm Tarenso” is my choice for japan, it was a mobile multiple rocket launcher developed by the Imperial Japanese Army around 1944. The system consisted of a 150mm rocket battery mounted on the chassis of a Toyota truck and I won’t take away to credit vinicius for his original post who it’s better explained than my old post.
