 Further marine companies and a weapons company would later be formed to augment the expansion of the force in the 1960s, and the abilities even expanded to VIP protection, and would also see the raising of its very own drum and bugle corps.The Marines would see themselves in action in securing the Spratly Islands in 1971 and in combating Muslim separatist forces and a strong New People's Army in the following years as the force became the Philippine Marine Brigade with the formation of the 2nd and 3rd Marine Battalions, the Headquarters Service Group, the 1st Provisional Tactical Battalion which saw action in Mindanao against Islamic separatists, and the Marine Training Group, later the Philippine Marines Training Group.To highlight these changes the force was, in 1976, renamed as the Philippine Marines.
