Well about your first part i.e Suicide bomber several times. The local dress of kashmiri with FAREN helps the terrorists to hide AK-47 easily. Infact the suicide attack was carried out by Jaish-e-mohamad, Laskar-e-tobba pro pakistani outfits, and haven't seen JKLF doing that. There was one more outfits named Hizbul-mujahedeen. JKLF wants freedom, but there was several outfits which were Propakistani.
Your second part if I remember was during Chera-e-Shariff and Hazzratbal mosque crisis. The first part was carried out by the terrorists about 200 in nos and they captured a small town, in which a famous Dargah of Chera-e-Shariff was there which was the symbol of the kashmiri hindu and muslims unity in Kashmir. The terrorists burned the Dargah and set fire to various houses (Kashmiri houses were wooden mostly with tin roof). Most of the terrorist were killed and several escapes including the commander, taking advantages of Fire Fighting operation carried out to save the locaal resident. The Pakistan and the terrorists then carried out propaganda that it was Indian Army who set fire.
Second incident was during HajratBal Mosque (mosque in which one hair of Prophet Moh is there in a bottle)when few dozen terrorist enters the mosque and IA surrounds the mosque for several days. IA never storms the mosque but carried out slow, negotiation for the terrorists to surrender.
India to had to face lot of problem because there is only one road Jammu-srinagar-leh road which is the heartline of the kashmir, connecting the valley from rest of the country. Another problem was the Pakistani leaders with speaches poisoning the minds of kasmiri youths, and the training camps in Pakistan occupied kashmir and even sending the Afghan fighters in the valley.
Moreover my friend you have to stop cross border weapon and terrorist path using Rangers, and second use of paramilitary forces and local police. It is because Army can never win the war with terrorism, and slowly they start losing the real capability, to fight war, not to fight terrorist. Even if Army killed hundreds of terrorists, the children of dead terrorist pick up the arms. So there is no end to it, my experience says it can only be defeated with tight security in border by Ranger, capable local network of Spy Agencies, and effective Police/paramilitary, with Civil Jurisdiction, so that no sane person would have to be tied on doubtful ground by the Army. I don't know about the conditions there but rules should be same there too.
I was only asking about the type of terrain, terrorists attack tactics- gurella warfare or Swamp attack in high numbers. local support, and the problem faced by the security forces. And about the air attack because its been carried out in Pakistani soil and not Afghanistan, and the border is sealed i supposed.
