1/200 Tatra 813 RM70

The RM-70 is the Czech version of the Soviet BM-21 multiple rocket launcher. It is mounted on a Tatra 813 truck chassis with an armoured cabin. An advantage of the RM-70 over the BM-12 is that it can carry a second pack of rockets. These can be loaded automatically, allowing it to shoot two salvoes in quick succession. The RM-70 was introduced in 1971 and served with a number of armies in the Warsaw pact and all over the world.

Wikipedia has more information about the original.

This item consists of one model on a sprue. The launch tubes and a bulldozer blade are separate items on the sprue. To mount the dozer blade, the towing hitch (coupling) on the front fender must be removed. To mount the shovel, cut the shovel and D-shaped sprue from the main sprue and glue it under the cab, right back to the chassis rod - see the 3d sketch.
The launch tubes can be mounted pointed in any direction.

The model is simply a scaled-up version of my 6 mm scale model. No extra detail has been added.
