India has successfully formed China as a regional enemy. India will keep buying weapons to confront China as well as Pakistan, so while India will acquire more and more weapons to be used against China and Pakistan, it's in the best interest of Pakistan to develop own defence industry for every need of its military instead of militarily trying to match India in numbers or closing the gap but bear in mind that keeping up with technology is important. As an example, India has a massive Navy as compared to Pakistan navy however, Indian Navy has to deal with PLA Navy also in the region. In case of war, India cannot divert 100% of its military assets towards Pakistan, while Pakistan has this luxury especially when western front is being secured with fence, surveillance equipment and up-gradation of FC. It's important to predict what percentage of Indian forces can be shifted from North-Eastern and Eastern fronts (facing China) towards Pakistan. How many IAF squadrons and which navy vessels can be spared facing PLAN and diverted towards PN.
Having said that, Pakistan's military equipment needs a lot of modernisation in Tanks (T-59, T-85), Artillery (older 105 mm, 122 mm 130 mm), Helicopters (transport and gunships) and Aircrafts (F-7 and Mirage III/V). A general rule would have been to get the older inventory replaced and after that raise newer formations, however Pakistan has been forming newer formations (LID, MIB, Armor Regts etc) side by side. PAF has formed new squadrons also (28 & 29). PN is inducting newer ships and in future more submarines.
IMO, the expectation from a military formation would be to have enough resources in troops and equipment to be able to carry out a designated mission successfully. One needs to look into several factors like if Strike Corps of Pakistan Army have the capability to go on offensive inside India and capture a major chunk of area like an important town or city. If FCNA has the required logistics to attack and continue the offensive inside IOK capturing cross-roads, peaks and towns as it's subordinate formations press on towards liberation of J&K. If Navy and Marines should be allotted a sizeable amphibious capability to be able to strike before Indian navy starts its build up near the creek area or further south of it.
Pakistan has produced a big arsenal of missiles and nuclear weapons for its defense. Nasr will be deployed in a defensive manner if a sector is threatened to be over run by Indian forces (armor probably). Its the offensive Operations that leaves a lot to be desired. The current COIN war may have produced a battle hardened Pakistan Army, but this was a war in our own backyard. Taking the war to the other side of the border is a completely different ball game.
