As far as I know hey show up only if they are after that HVT since long. Their own target with totally independent op & commands. Other forces like 19RR & 164Bn CRPF are regionally deployed forces who supported them. And you are right about local commanders that SG can't be called like SFs.
Some links I found regarding this op.
Today they killed an HVT Paki IED Expert just like they did in 2017.
Their last known op from the valley was on 21/11/2017 Magam, Handwara
It was also an op involving HVTs. They killed 3 Paki LET Jihaadis that day who infiltrated through kupwara few days back. It was a major op as quoted by senior JKP officers.
On the same day in another op involving 23 PARA & 21 RAJRIF along Kupwara LOC an Army Jawan was KIA where LET Jihaadis tried to infiltrate in which LET Commander Saifullah went to receive those infiltrators. Now whether he is the same Saifullah (Also a Paki LET Commander) who was killed 5 days ago in Srinagar or not, I am not so sure.
Interestingly 3 days before this Handwara op 6 Paki LET terrorists (Including Nephew of Zakiur Rehman Lakhvi) were killed in in Hajin, Bandipora involving IAF Garud commando Jyoti Prakash Nirala who was KIA in the op for which he received Ashoka Chakra posthumously.
Total bloodbath that week.
