Marmon Crowther

Colonel Marmon Crowther was the commander of the elite 21st Space Assault Battalion, nicknamed the Black Daggers.

Personality and traits
John-117 initially suspected Crowther of wanting to save his own reputation when he was reluctant to use the Spartan-IIs in operations after he found out they were minors and blamed the Colonel for not giving the Spartans more commanding roles within the battalion. After Crowther confided to John-117 that he was weary of Hector Nyeto - whom he suspected of having Insurrectionist sympathies and wanting to kill the Spartan-IIs - however, he became more accepting and respectful of the Spartans in general, and John in particular; the latter especially saw him as a father figure and a role model for commanding.

Trivia
It was Crowther who promoted John-117 to the rank of Master Chief Petty Officer, 4 full ranks, which was something unheard of even in 2526.
