sir arming and equiping them after conflict will not work . MYM's job is done they have pushed unwanted people into BD already lets see what will happen next when india will push muslims of assam into BD after CAA fully implemented . as a pakistani what i see during that conflict times BGB was not ready nor well armed . while at least BGP have basic needs filled by their gov . its not secret that BD have very low defense budget and shear of BGB will be peanut in it .BGB itself is a fighting force. This started when it was called EPR or East Pakistan Rifles which was a mixed troop consisting of Bengali, Pathan, and Punjabi. Guns that you see in the pictures are not relevant. In times of border tensions, they are quickly equipped with better weapons.
Our BGB is capable to fight the regular army of Burma whenever needed, but not against heavy weapons. BA troops usually do not come to their support immediately but are kept on standby in Ramu. about 50 km from the border.
BGB fighting history is glorious against the Indian troops. BSF troops do not really challenge our BGB. BSF is purely a border security force but not a fighting force.
