how become a in indian army brigadier
hey,
there is no such way to direct become the indian brigadier, you will get promoted to that post but before that you need to undergo through following under post like you will be commisioned in army after completing your training as an Lieutenant and after 2 years of service you get promoted to the caption then after 5 years to be a major and next 7 years to be a Lt. colonel
after all this there will be a board for the further promotion to colonel if you will pass the board you will be the colonel and command a unit,after 7 year there will be an another promotion to brigadier.so it takes upto 20-25 years to be the one.
good luck!
