That's the only option we have , Chinese Artilery is strong , they are in relatively plane terrain , and they also Deployed there arty in high terrain also , there projectiles can do a 90 Degree vertical dive , they can loft the projectile in much more steep angles but with reduced range and that is enough for India. 200Km projectile can launch in steep ballistic trajectory and later manuver through the air and finally do a vertical strike , and we even don't have CRAM. Don't know our planner's counting on the terrain or what . Most likely they opt for airpower to neutralize those Artys , . Our artillery systems are limited capabilites in that terrain .
