Hii,

Yes, there is a defense quota for certain MBA schools that accept applicants through the MBA CET. This implies that certain colleges may grant special seats or benefits to dependents of military personnel (air force, navy, or army). These seats are set aside to support those families.

There is a cap on the number of seats, though, and not all colleges provide this quota. Verify the regulations and required paperwork of the particular college if you wish to apply under the defense quota.
