There are huge doctrines that have been studied for many years behind these tools, which we sometimes look at very simply. All the avionics, all ammunition used in these vehicles are redesigned in accordance with these vehicles, after first gen examples. Attack concepts, communication protocols and all other mission needs were created accordingly again.
Israel or Turkey, China or the US, global or regional; each of them advances these projects with field feedbacks and operational experiences. Therefore, their unique solutions are fed directly from these sources.
Pakistani air force seems to have given its logistics weight to Chinese companies in recent years. (Of course, geopolitical reasons of Pakistan and the unreliable attitude of the USA are very important in this regard, alongside internal political balances...) Therefore, Chinese trends in this area will likely serve as an important guidiance in Pakistan's creation of its own drone force.
Frankly, I disagree with the opinion that a force like the Pakistani air force does not attach the necessary importance to UAV systems. News flows in open sources can be misleading in this sense.
Especially in 2020, the experiences in Libya and Syria are not only against the asymmetric threats of the drones; If it can be supported by appropriate EW conditions, it has demonstrated its effectiveness in suppressing the air defense layers established for A2 / AD (which some of the most risky mission profiles...Although it constitutes a very important part of the air force training and only fleets based on this purpose are organized). In other words, no country can escape this reality anymore. These systems are now among the main combat elements, even under conventional conditions.
A great paradigm shift was seen with the use of manned aircraft before World War I. (It was first used during the occupation of Libya by Italy, if anyone here interested war history) 1 century later, we are on the verge of a new paradigm shift. No country with strong geopolitical claims will want to stay behind this time.
