I believe it needs some change in tactics. Experts can place their views too.
1> Pervasive surveillance using: a> LORROS, b> High mast mounted cameras and IR/Thermal imagers, c> Armed MALE drones, d> Swarm quadcopter close to the LoC fence area.
2> Ability of BSF, Army, CRPF, or any force operating on LoC patrolling duty to call in a drone strike at will.
3> Keep the PA and their jihadis under constant artillery barrage.
4> Rotating tank/bmp turret based fixed robotic pill boxes with large ammo case and autoloader + ready to fire ATGMs placed at strategic and tactical heights along the LoC and at the command of Havaldar/ JCO level soldier to use at will. This can be tied in with the LORROS, masts, and drones for accurate targeting.
5> Use of armed small UGVs close to the LoC and at known infiltration points.
6> Use of cheap suicide drones. Not the harp/ harpy kind but something that can loiter for max 10-15 min and can quickly be brought down on the enemy, and in large numbers.
