Comparing: Spähpanzer Ru 251 vs. Indien-Panzer

The vehicle was developed on the basis of the Kanonenjagdpanzer 4-5 tank destroyer by the Henschel company in 1964. The tank was planned to replace the obsolete M41 Walker Bulldog vehicles used by the reconnaissance battalions of the armored divisions in the German Army. The tank never saw mass production, but some technical innovations were applied later in the development of other vehicles. The total number of prototypes built is unknown.

The project was developed as a medium tank for the Indian Army. The work on the project was carried out by Porsche, Daimler-Benz, and Zahnradfabrik AG of Friedrichshafen. However, the vehicle was deemed to be too complicated for production in India, and the project was canceled.
