I found only the T-70 and, obviously, just missed the self-propelled gun based on the APC.Christmas was a month ago, you know...
Maybe you could choose the model you REALLY want to get, because it actually takes me 2/3 weeks to produce a functionnal unit.
Maybe try a tactical missile? There is a Luna-M in the list of drawings, but there is an earlier and simpler version – just "Luna", based on the PT-76

And yes, I will explain how this can be applied. These things with a rather limited range, but a large charge weight were intended mainly for the delivery of nuclear warheads, although they could use "normal" ones. That is, it is a cheap nuclear missile that can hit a neighboring tile (and only one tile is hit, but strongly).
At the same time, a clash of nuclear powers with Cold War technologies would have involved the use of a large number of tactical nuclear weapons, a colossal amount of them had been accumulated. And one of the features of such a war is just the problems with creating a stable defense or its extreme high cost, for obvious reasons. In other words, this is a very different war compared to the Second World War or typical modern operations against countries of the second/third rank.
