Stressing on integration between Army, Navy and Air-Force, Chief of Defence-Staff-General Bipin Rawat said it is important to ensure that "1+1+1 combine" of the three services adds up to "5 or 7 and not 3" through synergised action. Gen Rawat, who took charge as CDS, said the synergised-effort of the services should not be the sum of the whole, but much more than that.
