BTO ( RANK 1.8 ) ( 🚩 USSR ) (Self-propelled multiple rocket launcher) (BM-8-24)

🧭 BM-8-24 on T-60 Chassis – Overview and History
The BM-8-24 was a Soviet self-propelled multiple rocket launcher mounted on the chassis of the T-60 light tank. Developed during the early years of World War II, the BM-8-24 represented an effort to create a fast, mobile artillery platform capable of delivering concentrated rocket fire against enemy infantry, fortifications, and light vehicles. It was part of the wider "Katyusha" rocket launcher family, famous for its psychological and destructive impact on the battlefield.

By utilizing the T-60 chassis—already being mass-produced—the Soviets quickly converted surplus or underarmed light tanks into highly effective mobile rocket artillery units, increasing firepower without building new vehicles from scratch.

🛠️ Design and Development
The BM-8-24 system was based on a 24-rail rocket launcher designed to fire M-8 82mm rockets, mounted on the hull of the T-60 light tank. The T-60 was a small, lightly armored tank originally intended for reconnaissance and infantry support, but by 1942 it was increasingly obsolete in direct combat. Instead of scrapping it, the Red Army repurposed it for indirect fire support.

The launcher rails were mounted on a rotating and elevating frame, replacing the tank’s turret. This modification gave the vehicle the ability to deliver a salvo of rockets quickly and relocate before enemy artillery could respond—a hallmark of Soviet rocket artillery doctrine. Although the chassis retained the T-60's original mobility, the added weight of the launcher and rockets made it less maneuverable, and its braking system was known to be relatively weak.

⚔️ Combat Use
The BM-8-24 saw service primarily during the 1941–1943 period, particularly on the Eastern Front. It was deployed in artillery support units, where it could deliver suppressive rocket barrages before infantry or armor advances.

Combat roles included:

Rocket artillery support – suppressing enemy infantry and light fortifications.

Mobile fire missions – shoot-and-scoot tactics to avoid counter-battery fire.

Urban combat – firing rocket salvos into enemy-occupied buildings and positions.

While its armor was minimal and its launcher vulnerable to small-arms fire and shrapnel, the BM-8-24 was valued for its psychological impact and mobility. As the war progressed and more advanced launchers on better chassis (like BM-13 on Studebaker or ZIS trucks) became available, the BM-8-24 was gradually phased out.

🔧 Notable Features
Compact, mobile rocket launcher based on a tank chassis.

24 launch rails for 82mm M-8 rockets.

Light armor provided minimal crew protection.

Employed hit-and-run artillery tactics.

Simple, cost-effective adaptation of obsolete light tanks.
