CRPF is a worst case scenario. Assam.Rifles, BSF, ITBP are good fighting force. If the need arises we can operationally train them to the needs of the army incorporated into infantry regiments. Those 3 forces can add around 200k extra "able" troops if we remove the flaps on them.
We should invest more in satellites, drones, surveillance equipment and use the army when and where required with precise intelligence.
All three have their operational roles during war, one specific area or border given to them and can not be pulled out from there during war.
The problem is that they can not be trusted and relied upon, not trained and equipped to defend those borders without Army deployment ... BSF or Assam Rifles can not be taken to Ladakh by denuding Paki, Bangladesh and Myanmar borders.. nor the border be left to them during war,,
There is a requirement to mesh them with Army plans, equipment, training and to be officered partially by Army. Communication is the biggest problem. Even in Kashmir valley CRPF and RR can not communicate with each other over radio except on open Motorola..
All these problems can only be overcome if all CAPF recruits including officers are trained by Army, they serve for five to ten years in the Army and then shift to CAPF,,, then they can have one month's annual training under Army ... the similarity of basic weapons, equipment and communication is brought about.
Then only, Army can partially shift their forces from BSF sectors..
