I myself wrote about this a couple of months ago:(http://www.vifindia.org/article/2012/july/16/naresh-chandra-task-force-s-report-on-national-security-an-appraisal)
The recommendation that a four-star officer be given a fixed two-year tenure as Chairman, Chiefs of Staff Committee to bring stability and continuity in coordinating tri-service matters makes eminent sense.
The sooner it is implemented, the better it is since the current post of CISC (Chief of Integrated Defence Staff to CoSC) is nothing but a waiting room for officers biding their time to take over as C-in-Cs or Army Commanders. A cursory glance at the past three incumbents as CISC will give an idea how this post is treated.
In January 2011, then Vice Admiral DK Joshi, (the current Navy Chief) joined as CISC. In exactly six months, he left for Mumbai to take over as C-in-C, Western Naval Command. Vice Admiral Shekhar Sinha took over from him only to shift to Mumbai as successor to Adm DK Joshi who was elevated to Chief of Naval Staff on 1st September this year. Vice Admiral SPS Cheema succeeded Vice Adm. Shekhar Sinha as CISC from 31st August.
