Yea, doesn't sniper pod help in A2A as well tho ?The initial IRST had issues in the track part. That got solved, and now a 4th gen of the intial IRST that came in 2004 has been installed with the new Blk62 upgrades.
The MS-110 is a successor to the DB-110 and the two perform separate distinct roles.
The IRST is for A2A use, the DB-110/ MS-110 is for ground reconnaissance.
Btw a sniper pod can be very useful too in A2A
The need of Sniper pods, BETTER sniper pods was highlighted in the prime example of Zarb-E-Azb when Turkish one was preferred over Chinese one thanks to shortcoming in the chinese one that comes as package for thunder even tho Chinese one is used and has got upgrades since at AVIC.
