The number of Ranpur in the Satkav is 1,013 units, of which 1,086 units are owned, but the quality is still far from expectations. Of the number of existing ranpurs, 248 units are in limited condition or not, all automotive, weapons, and communication systems are in good condition, 716 units are lightly damaged and 122 units are heavily damaged, so that the percentage of the existing ranpur units is only 24.8% which are operational. while the other 75.52% are not ready for operation. Of the 1,086 ranpur units owned by the cavalry, only 15.9% were classified as new defense equipment made above 1980, while the remaining 84.1% were old defense equipment with years of manufacture below 1980, which were technically unfit to meet operational needs as a raider or function. security.
