Haha Good joke.... Even USA is thinking of taking the scope out of sniper rifles for fear of damage in battlefield and tree branches/muck damage... (sarcasm)This makes it vulnerable to small arms fire and it can get damaged in rough terrain where the ground is uneven.
But hope u get the point, the necessity is similar in Rudra/LCA too (identification/long range Surveillance/Aim laser designator and laser illuminator/laser range finder/area scanning/TV & thermal imager/Haze penetrator) etc.....
Look Apache nose marked in red (different product, similar role/characteristics)
Ideally placed in maximum field of view, since bottom has gun that leaves nose as best spot.
