World most sophisticated armies dont invade countries having up to date air superiority fighters, air defence systems and AWACS. Invading countries like Iraq and Afghanistan with Airborne troops is easy only after achieving air superiority.
US 82nd Airborne Div moved in trucks with French motorized forces into Iraq in 1991 and the rest of it provided security to KSA Royal Family and after that protected flanks of allied armoured columns moving into Iraq and Kuwait , they were not para dropped.
Pakistan Army has limited Air Assault ability using helicopters to insert Regular infantry, but thats just a section in one helicopter (UH-1, Puma, other bell series) since heavy helos like Chinook and sea stallions are not available, a platoon maybe in Mi-17 but that would require almost 5 -6 Mi-17 for a company level assault and roughly 25-30 Mi-17 for a battalion sized air assault.
SSG, SSW and SSG (N) are all SF and dedicated Airborne troops.
SSG/ SSW/ SSG (N) best role is to have 25% strength deployed behind enemy lines at all times. COIN and Domestic Ops should be dealt with other special forces of para military and police under interior Ministry.
Basic Commando forces like SSG need to operate BEL and can have 6-man teams inserted in enemy territory disguised and living as civilians with support and direction from ISI contact for recon and spec ops. They need to be qualified oral, reading, writing in foriegn language of that country, which could be hindi or afghani etc
1 X team leader
1 X 2IC
2 X Medic
2 X Regular Commandos
All qualified in sniper, demolitions, CQB, communications and EW courses. This way they can be split into two 3-man teams also retaining all capabilities of leadership and medical support.
Staying on a 1 month or 3 month or 6 month tenure in enemy country as long as it takes a specific mission to complete, they can acquire weapons and other military supplies from resistance groups, smugglers or other contacts made by ISI. They can live under duplicate alias and ID's, working minor jobs in day time or as students. The ISI contact keeps giving them monetary support and communication with HQ while they give ISI feedback on the mission stats.
Similarly, SSW teams on same lines can go after enemy Air Force targets while SSG (N) teams can go after enemy naval targets.
Once the mission is complete, the team needs to head back towards the border for extraction which could be through land, air or sea otherwise cross the border at some specific point etc.
Unfortunately, SSG is Pakistan's forefront AT force, while its a much more capable force but its sent to do jobs that are deemed impossible for other forces.
