The terror of Fulda for a while. The one way the Americans could outproduce tank destroyers enough to turn the Red Army at its peak.
Germany just did it like this:
Sorta the German answer to the BMP. Just stick a 106mm recoilless rifle on those HS30 APCs. One 106mm in each mech inf platoon. Turreted gun on those is 20mm.
Casemate tanks in the background in the second pic are
Kanonenjagdpanzer. 90mm gun. Each mech inf batallion would have eight of those in two anti-tank platoons. Both those and the 106mm on HS30 were introduced at the same time in 1966, the same year the Soviets introduced the BMP-1.
Those pictures were taken in 1970, the same year the HS30 were replaced - only four years after the above modification. Base HS30 were replaced with Marder, the 106mm with Milan ATGM. The Kanonenjagdpanzer were moved to dedicated anti-tank battalions with infantry divisions and later - in the 80s - moved to serve as infantry fire support in individual 7-tank platoons supporting territorial army infantry regiments.
While there were 106mm on Munga jeeps for light infantry at some point, they were replaced even earlier - starting in the early 60s. Original trials were for Munga jeeps with SS.20 ATGM, what was later introduced was a platoon of Cobra ATGM for every light and medium infantry battalion. That freed up the 106mm for mounting on the HS30 instead.
