22 Apaches may not be enough for a full blown 2-front war but they should be more than enough to snuff out jehadi infiltration very quickly with minimum casualties.
Not sure how effective attack choppers are in a MANPAD infested ground war, specially in open terrain. They seem more suited to hide-and-seek type combat in terrain which provides radar and visual cover--urban, forested or hilly/mountainous areas. Their USP is being able to see and engage from a distance without themselves being seen or heard.
The apaches are experts in tank killing. The plains of Punjab, Rajastan can prove pretty messy for enemy Armored units in the presence of these.
The Attack Choppers usually travel in groups, so if a lone MANPADS team tries to engage them, irrespective of their missile's hit they will be toast by the reminder of the birds.
This is not the case when MANPADS engage strike Jets.
This puts in a lot of pressure on the sneaky MANPADS squad and practically can deter them from firing. The choppers like Apache are very good at counter measures against MANPADS and are more likely to survive then any other type of a chopper.
That said, even Super Cobras are very good.
