I'd be interested if anyone has information on the doctrines for deploying and using these, and similar, tank chassis -based SP Katyusha launchers.
The Soviets had several models of tracked prime-movers for artillery (S-2, YA-12 and STZ-5 being good examples). For front-line guns like small 45mm and 57mm AT guns and 76.2mm infantry guns they often used the armored S-20 Komsomolets tractor. And they also sometimes used redundant light tank hulls as artillery tractors.
But none of these, with the possible exception of the S-20 Komsomolets, was expected to engage in actual combat. The S-20 had a bit of armor and was equipped with a DT LMG, but was really seen as a prime mover that had to go into harms way to do it's job, rather than as a combat vehicle.
Then we have this idea of a light tank chassis with a Katyusha launcher. The M-8 rocket of the BM-8 Katyusha (as mounted on the T-40 or T-60 light tank chassis) had a range of about 6km. But the vehicles are often shown with the launcher at a lower elevation -- almost horizontal. So I'm wondering were these were considered direct-fire weapons, to be driven up to firing positions within sight of the enemy, hence getting some substantial value from the armored protection? Or were they considered indirect fire weapons, to be fired at longer ranges at map targets, but with tracks to get around in the mud and snow?
Anyone got some sources on this?
