descendant of the 2nd Regiment of Foot. Cavalry and RTR order of precedence The majority of line cavalry regiments in the British Army now form part of a wider administrative formation called the Royal Armoured Corps, along with the Royal Tank Regiment. The two cavalry guards regiments are part of a separate administrative formation called the Household Cavalry. Infantry order of precedence The infantry is ranked in the order of Foot Guards, Line infantry, Rifles. The Royal Marines, as the descendant of the old Army marine regiments of the 17th and 18th centuries, were included in the Order of Precedence after the descendant of the 49th Foot (the Royal Gloucestershire, Berkshire and Wiltshire Light Infantry (RGBWLI)), which was the last line regiment of foot formed prior to the formation of the Royal Marines, when not on parade with the Royal Navy. On the completion of the infantry reorganisation in 2007, the RGBWLI, along with the Devonshire and Dorset Light Infantry, the Light Infantry and the Royal Green Jackets, were absorbed into what has become part of The Rifles, and moved last in the Order of Precedence. As of April 2008 the Royal Marines are considered to no longer be a separate arm of the Royal Navy, but rather an integral part of it. Therefore, they no longer have a place amongst the (Army) infantry regiments and now take their place as part of the Royal Navy and parade on the right of the line. Even if there is no other Naval contingent present they are the senior formation on ceremonial occasions. If other contingents of the Royal Navy are on parade, the Royal Marines take their place after them, but before all army regiments and corps.
