During the operations against Pakistan in December, 1971, Group Captain Kottavathukal Thomas Abraham was commanding a Signals Unit in the Western Sector. He was in control of an Air Defence Direction Centre and a number of Ground Control Interception and Early Warning Units. A number of Air Defence Artillery Brigades and Surface to Air Guided Weapons Squadrons were also placed under his functional control. In addition, a completely new system, including a chain of Observation Posts were inducted into the existing system. With sound planning, hard work and inspiring leadership, Group Captain Abraham accomplished all the tasks creditably. The ground work laid down by him prevented the enemy Air Force from carrying but any productive strike. When enemy aircraft attached and damaged some equipment of his unit, he made it possible for the unit to resume operations with commendable speed and also to handle the heavy volume of operational traffic.
Throughout, Group Captain Kottavathukal Thomas Abraham displayed professional skill, leadership and devotion to duty.
