I understand what you say above makes sense and no organisation will talk about their failures
and only reluctantly talk about their success as they want to avoid media scrutiny. However sooner or later old boys talk for eg BBC has documented the hostage taking in Iran Embassy in London and full view of the media the SAS carried out the successfull operations. I had read about two operations which may have been carried out by SSG. I maybe wrong one was when a large group of Special Forces operatives were dropped behind Indian Lines to blow up their air bases however they were landed in the wrong place so could not carry the ops. I am not sure whether they were captured or successfully exfilterated back. Another operation I remember was the Hijacking of a Pan Am aircraft in Pakistan which was stormed by the Special Forces. A lot of passengers died during the storming.
Maybe some ex SSG chaps on this forum may wish to share his experiences not neccesarily India centric with civilians like us.

Any SF operator worth his salt will tell you this that the proportion of failures is higher than the successes in Special Operations. This is due to the fact that most special operations by their nature are difficult and very risky.
Another thing to keep in mind is that you cannot compare the successes and failures of two SF outfits simply because one may have been employed a whole lot more than the other.
SSG have had their fair share of successes and failures. Among the failures that you mention, the 65 operations were indeed that, however there were very many mistakes committed in the employment of SSG. About 150 operators were dropped on three IAF bases and 100 or so were captured (10 or so KIA) and the rest exfiltrated.
I don't want to give a very detailed account of what led to their failure, however the biggest one was loss of initiative and improper employment. The SSG HQ was given an ultimatum to send the teams into India on the first day of the declared war when the Indian vigilance was the highest. They were sent in without any support once they were in and were given no way out. The fact that not one of the operators opted out is a testament of discipline and dedication to service and Pakistan. Lets not forget that.
During operation Qiyadat at Siachen, SSG suffered reverses as well and we can blame improper planning and an underestimation of the enemy strength.
PANAM issue was one due sheer bad luck. The newly trained SSG CT team had decided on moving against the plane but before they could, the aircraft lost power and the hijackers started shooting the passengers out of panic. This led to a hurried SSG intervention without having cleared the passengers out of harms way...as a result many died. It was sheer badluck in my opinion.
On the success side, the 1973 Baluch CI operations were spearheaded by the SSG and they were able to contain those very effectively along with the regular Army. The same goes for the extensive SSG support for operations inside of Afghanistan throughout the Soviet occupation of the country. The advising on the ground and training was again spearheaded by the SSG. Many successful operations in Siachen have been led by the SSG.
On UNPK duties, as part of MONUC, SSG operators have led the way in combat.
The issue is that if you want newspaper headline type of successes then there may not be many, however from the standpoint of importance, the SSG has done more than its fair share.
Let me end by stating that in 1966, it was decided by the PA to disband the SSG owing to its failures in the 65 war. A complete anlysis was done by the GHQ on these ops and it was found that it was not really the SSG capabilities but unrealistic expectations and improper employment that led to failures. When senior commanders from SSG started getting into the higher echelons of the Army, this perception was corrected greatly and SSG has been used very effectively in many operations such as those I have highlighted above. The SSG performance in the 1971 war was very good (but was overshadowed by the fall of EP). Otherwise in West Pakistani border and even during the CI ops by the SSG Bns, success rate was very high.
