brother,
the terrain and height we intend to use them is same as Afghanistan where they have been extensively used and still being sued
time and again they and their transport cousins have been proven to be robust and heavy duty work horses of the military's that are using them.
they offer more fire support than cobras and carry same number of troops as Huey's so they double the job of 2 copters and some. but lets not get ahead of ourselves , India might see this proposed deal as the end of the world and arrange visits to Russia to have this deal cancelled. then it will be same American Huey's and cobras we will have to go for.
I dont know why you decided that they are slow and cant operate at higher altitudes.
they beat our cobras in every aspect, in speed, range, rate of climb and service ceiling. I will trust you to look up the data yourself.
the Hinds beat cobras by big margin. only your T-129 beat it slightly in rate of climb and ceiling... other than that the platform offers a large variety of roles in in one package.
