Kyle Netreba is the current Commander In Chief of 2nd Fleet Mars. Among the triumvirate that commands the UEF Navy, he is the least "military" officer. Originally trained as an engineering specialist (software subspecialty), he switched to the command track after he demonstrated good leadership skills during an incident in which he had to take command of a frigate after its command staff died during combat. His market-based algorithms for logistical handling earned him the praise of the Council of Elders, a lasting relationship with scientist-elder Svetlana Henriksson, and eventually a place in the Admiralty.

His leadership style is unorthodox. He has structured his command less like a traditional fleet, and more like a design bureau, hand-selecting 2 Fleet's ship captains for their ability to think and act independently. Yet the outbreak of the war saw an abrupt shift in his disciplinary approach, including crackdowns on traditionally lax Martian standards. Some suspect Netreba sought advice from Admiral Calder on wartime conduct.

During the war against the GTVA, Netreba found himself in a difficult position. Calder and Byrne used his fleet as a reserve asset pool for their own very different priorities, and Netreba feels increasingly dissatisfied with this position. His cooperation has not always been rewarded, either in terms of assets for his own OrBat or rest and repair time for his crews and ships. Between having to guard assets that are nominally in 1st Fleet's remit, and supporting offensive actions by 3rd Fleet, his own command and the abilities of the people within it are being wasted, a state of affairs that he feels threatens 2 Fleet's effectiveness as a unit.

While the Admiral is unsatisfied with Admiral Byrne's strategic directives, and much more comfortable with Admiral Calders' aggressive strategies, his ability to work with Admiral Calder is limited. Given their vast differences in command styles, this comes as no surprise. Where 2 Fleet relies on each element acting independently in support of a broad strategy, the Jovian Rim Fleet relies on detailed pre-battle planning and pre-rehearsed maneuvers that can be executed with a minimum of forethought. Whether or not the two commands can overcome these structural differences and produce results when acting in concert will probably be one of the deciding factors in determining the war's outcome.
