They have lots of toys. Mobile missile launchers are hard to find, though, especially at night. Probably a significant number of these missiles could be successfully launched in case of attack, which they expect will come during the night to begin with.

Hard to find from the air. If India has eyes on the ground, it's a slightly different story.

India will be watching the skies at all times with their low-level radar units...:

...and their UAV's like the Nishant, complete with TV/LLTV cameras, FLIR and IRLS systems:

A guided missile launcher is the size of a semi truck. A little camo and *poof* it's gone. Just like Iraq's Scud launchers where several were able to launch in spite of extensive aerial surveillance, and that was in terrain where it is harder to hide things.
