- "As you know, I've studied our battle lines for some time. I developed an algorithm to counter all our tactical tendencies, with the hope we could use it to shore up our weaknesses."
- ―Captain Rex
A strategy algorithm was developed by Captain Rex that outlined battlefield tactics for the 501st Legion. Rex only ever shared the information with two of his men: Echo and Fives. After Echo was severely wounded and captured by the Separatists during the Battle of Lola Sayu, Admiral Trench used the information to his advantage during the Battle for Anaxes.
