The Gear Krieg background features more then just cool walkers and some Infantry ideas. The setting is oozing with cool superscience ideas. One of the most interesting concept for me are the super science tanks.
Tiger (P) EXSThe Tiger was the first vehicle equipped with guided missile systems. Two Tiger (P) prototypes were send to Africa in late 1942. One featured the R-104 Lenkrakete. The so called Tiger (P) EXS was deployed alongside a conventional (P) Tiger and a Panzer III L.
The Luftwaffe had been extensively involved in developing guided weapons to be used in precision bombing. Radio and later wire guided methods had be researched and deployed by the late 30's. With the encounters of heavy armour in Russia a desperate need for an effective and accurate anti-tank system was created. Coupling the advances in rocketry and guiding systems, it became feasible to mount a guided rocket system on a vehicle-sized platform.
The first to do this was the Tiger EXS, its spacious turret providing the necessary room to mount the bulky guidance equipment. From there, further refinement allowed a infantry portable system to be produced. The R-104 needed a crew of three to operate and could be either wire or radio controlled. Fired from emplaced positions, they proved highly effective against enemy armour. The first walker mounted guided rocket was the R-92 Lenkrakete.
The above conversion is based on the wonderful Flames of War Tiger (P) kit. I used some GZG SF pieces to mount the rocket. The crude Radar dish is also from GZG, while the rocket itself is from Old Crow. I also added a Peter Pig crewman and some jerrycans.
