Republic Admirals wore grey uniforms, with their rank insignia made of three red squares in a top row, and a two square row of blue underneath in a bottom row. The ranks within the Republic Navy were somewhat unclear, but there were simply six concrete ranks that can be ordered, with Admiral being the highest rank in the Republic Navy, and Pilot being the lowest (as part of the Starfighter Corps). These officers were then filtered into the ranks of the Republic Navy. Therefore there were many officers such as Yularen who were already serving the Galactic Republic when the Clones first came. They did, however, have some groups of security, the Senate Bureau of Intelligence amongst them.
The Galactic Republic did not have a full military or Navy prior to the Clone Wars.
