Which means both Alpha and Cody have ties to Anakin when he was still a padawan (commander).

The Battle of Aargonar (Republic #59: Enemy Lines) and Praesitlyn (Jedi Trial) were two battles that Anakin took part in without Obi-Wan Kenobi. Cody took part in campaigns such as “Aargonar, Praesitlyn, Paracelus Minor, Antar 4, Tibrin, Skor II, and dozens of other worlds from Core to Outer Rim”. In the case of Alpha, he and Anakin knew each other almost from the start of war and worked on various occasions, from Defense of Kamino (2 months after Battle of Geonosis) to Battle of Boz Pity (5 months before RotS).

The source material was limited, and so direct interaction between Cody or Alpha and Anakin.
