Besides troops from the Northern Light Infantry, soldiers from 31 Azad Kashmir Regiment, 24 Sindh Regiment, Frontier Force Regiment and artillery units participated in the Kargil operation, Hussain said.
Hussain, who based his book on interviews with officers who participated in the fighting in Kargil, dismissed Musharraf's claim that the operation was a success.
"It was a success only till Pakistani forces came face to face with the enemy. In winter, both sides abandoned their positions under a recognised procedure. Our troops crossed the LoC at a time when the enemy was not present. Our troops were not even informed why they were being sent across the LoC," he said.
"I asked commanding officers and brigade commanders about the aims and objectives of the operation but none of them had answer," he added.
