The 237th Legion is a legion in the Grand Army of the Republic.

​

It is led by clone captain CT-3651 "Riot", and Jedi General Kael Vero. The Commander title has yet to be filled following a disaster earlier in the war. As such, Clone Captain Riot acts as de-factor commander. Supporting the Jedi General and his Captain is Medical Clone CT-3810, "Aten," CT-6521, "Wail," and a legion of clones. General Vero considers the three aforementioned clones to be his inner circle and trusts them with his life. ​
