It's highly likely, training is a major factor. For instance, most state police forces don't even know how to hold a weapon...let alone firing it in an active-shooter situation. During 26/11, Marcos reached the spot but couldn't encounter the terrorists except for evacuating a few hostages in empty floors where there was no hostile presence. Even the NSG took 3 days to eliminate em. During the Pathankot attack, despite Garuds presence in the IAF base, NSG had to be flown in from Manesar and it literally took us 4 days to eliminate 6 attackers followed by a 5 day clean up op. Our strategy has always been to wear down the enemy and make em run outta ammunition prior to an all-out assault. On that note, even Pakistanis have eliminated way quicker during such attacks like the Peshawar school massacre where SSG eliminated all 6 attackers within a day
IAF has also claimed to have shot down higher number of aircrafts during simulation and joint exercises with the west but that's simply not true and is for domestic consumption while our audience go gaga over it. If you see videos of our joint exercises, even our SF rappelling down from the choppers is sloppier than some regular western units
In regards to the emergency landing of AH-64, it's more likely to be training over a malfunction since Apaches have a pretty good reliability record and these are spanking new. Coupled with shoddy maintenance, I wouldn't be surprised if we see crashes of western equipment
