DRDO basically put in their mouths more than they could chew. Its illogical to make a weapon system and expect the armed forces to use them as per DRDO's visions, it means putting cart before a horse! By the way which AAD system you have mentioned here? There are NONE for use and deployment. In fact Indian AAD is the oldest and out-of date even by Bangladesh Army standards. Shame on you for boasting about nothing. DRDO cannot even design a decent pistol or carbine for the forces, taking of making missiles is a far cry.
