@arnabmit,
Mules are cheap and reliable and they cannot be replaced from Indian terrain same a men as fighting unit..
True for now. There is no way the IA can afford to replace the mules or human porters with helis on a large scale.
But 10-15 years down the line, We'd be a powerhouse of a country with a defence Budget of $100-150 Billion facing the new superpower with Defence Budget of $400-500 Billion. The massive budget of the Chinese will allow a disparative force projection capability, both in terms of deployment numbers, as well as in terms of speed of deployment.
Even now, with their rather limited Airlift capability, they hold 3 airborne divisions (under the 15th Airborne Corps), which operate as part of the Rapid Reaction Force of PLA, responsible for fast deployment into hot zones. As of now with their limited ability, they'd struggle to deploy even one airborne division, let alone maintain it by air. In comparison, we fare much better, at the moment we already hold a brigade solely with air supply, while most of NE outposts too are air maintained.
But By 2020-25, the PLAAF and PLA army Aviation will have expanded enough to mobilise much larger numbers and maintain them by air on a sustained basis. This will also definitely lead to an increase in their speed of deployability, and for the IA will necessitate very nimble and swift responses. In such a situation, slow moving supply lines, will cripple our ability to respond to a fast developing situation.
We'd do well to invest in newer, even unconventional means of logistics supply, if it can increase the speed and quantity of logistics supply. Any new initiative taken now will only develop fruits a decade down the line. Else the IA might find itself outflanked by the enemy because it couldn't manuevre quickly enough.
As the saying goes....
