Bikram Singh had Monday described the killing of two Indian soldiers - one of whom was beheaded - by Pakistan troops as "an unpardonable act" and said his forces reserve the "right to retaliate".
Army Day is celebrated Jan 15 every year in recognition of Lieutenant General K.M. Cariappa's taking over as the first commander-in-chief of the Indian Army from Sir Francis Butcher, the last British commander, in 1948.
