Does anyone know where Gaijin got the stats regarding the BUR high-explosive rocket? I haven’t seen any info regarding the specifics of the round, other than some less than reliable sources claiming the rocket had a velocity of 650-700 m/s. I ask because I am a writer for the Tank Encyclopedia and I am writing about the Object 775.
I love the Tank Encyclopedia!
Glad you are a fan! I have been writing a lot about early-mid Cold War vehicles as of late.
BUR is the best shell of 775, look:


Indirect fire in arcade battles :P
About BUR itself, all I can find:
"The 125‑mm unguided rocket projectile “Bur” was developed at Research Institute‑147 (chief designer A. N. Ganichev) in the early 1960s. It was intended for use with rocket tanks. The “Bur” projectiles were fired from a special tubular launcher‑gun of the D‑126 type, which was used in rocket tanks of the “Object 775” project. The same launchers were intended to be used with the guided missiles “Rubin”. To stabilize the “Bur” missile in flight, it rotated. The projectiles were loaded into the launchers using a semi‑automatic loading mechanism with remote control.
