1. Howitzers
India has been dilly-dallying over artillery guns for close to 30 years since the Bofors scam. Pakistan has inducted U.S. made M-109 howitzers.
Indian Express: United Nations data reveal that delivery of the M-109 A5 self-propelled artillery guns took place last year. The guns were transferred under the US Foreign Military Financing (FMF) programme that was granted to Pakistan for the fight against militant groups on its border with Afghanistan. Experts say these M-109 A5 155 mm howitzers give Pakistan a definite conventional edge over the Indian Army that is years away from induction of similar systems. Full news
2. UAVs
The game changers in the ****** war are the future of any credible Air Force. But PSU infighting delayed India's plan for 4 years. Recent articles on 8ak noted that Pakistan has started drone production with Selex Galileo.
3. Fighter Jets
While our military aircraft crash at a rate of 1.5 a month means a constant grounding of fleets (the Sea Harrier fleet is grounded after last weeks crash), Pakistan is upgrading their F-16s to the latest Block C/D with a little help from Turkey. Russia has also given the go ahead to China to give Pakistan the engines for the JF series fighter aircraft.
4. Motivation
The Pakistani people are united, not by their nationality, but by their religion and their constantly-re-inforced-by-the-mullahs/government view on Kashmir. Add to this the combat experience they are gaining in the ****** war and one can see that they would be a formidable force.
5. Funds
While India's budget is larger thanks to a better economy, Pakistan gets billions in equipment and training from the U.S., China and Islamic sympathisers like Saudi Arabia.
The list could go on to include helicopters, missiles, nuclear weapons. But at least India has the Arihant submarine. Well not exactly. Strategy Page article says that the Arihant was launched without a working reactor to scam the public in to believing that the government has something to show after sinking billions in to those projects.
