What was the callsign of Commander William Adama in Battlestar Galactica (2004)?

The callsign of Commander William Adama in the television series Battlestar Galactica (2004) was "Husker." This nickname was given to him during his time as a pilot in the First Cylon War when he was flying Viper Mark I spacecraft. The name "Husker" likely originated from the word "husk," which refers to the outer protective layer of a seed or fruit. This nickname might have been given to Adama due to his resilience, determination, and ability to protect and guide the fleet, much like how a husk safeguards the seed within.
