[1] Following its setbacks in the Eelam War III, during the ceasefire agreement from 2002 to 2006, the Sri Lanka Army adopted a change in its doctrine of deploying infantry in battalion formations when engaging the LTTE in future battles with introduction of the concept of Special Infantry Operation Teams (SIOT).

Selected candidates who had undergone a 44-day advanced platoon training course, continued with the SIOT course for additional weeks covering three months gaining skills in combined arms, joint warfare, and real-life exercises inclusive of close air support.

Battalion commanders were thus able to dominate a broad front with a depth of over 4-5 kilometers.

With the onset of the Eelam War IV, the army found itself in a high state of moral and an infantry adapted to jungle warfare, willing to fight at night which had been limited to its special forces till then.
