This may take two years or more. There are many people in the chain and it is never one person who takes a decision. Finally, the army headquarters tells the ministry of defence what it thinks. The ministry then goes for price negotiations at a multiple bidder level. Price, transfers of technology, financing procedures are all dealt with.
Some equipment is bought in a knocked down condition so that they can practice putting it together.
Because it is a cumbersome process, chances are that one person will never be able to influence the process. It takes ages to materialise, but it has its advantages too. The multi layered system of defence procurement itself is a safeguard against any manipulation. But what we need is a system that has safeguards but is not so slow. There is a definite need for revision of defence procurement procedures to combine accountability with speed of decision making.
