"Yes, our interceptors are more mobile and can fly rings around you if the pilot's good enough, but the Knight's the only suit I trust to win the battle while getting my squadron back to our Crown in one piece."
―Richard Ives, Royal Naval Ace

The RMS-05A "Knight" was a mobile suit developed and used by the Royal Sol Alliance, the fifth in a series of previous models developed in the years following the Unification War. It was the principle mobile suit of the Royal Sol Alliance Navy in A.U. 47.
