Comms. Officier is an unlockable helmet (i.e. Specialization or class). It ultimately allows the Trooper and his squad mates to use a number of handy active support Abilities, generally enhancing any army's performance.
A cheap way to get minimal potential of a CO while picking another class, is to get a Radio, as it grants +1 Communications.
Comms. Officiers start with +5 Communications, and get +1 with each level-up. This specialization serves solely to provide this vital global Stat and does not increase support ability use rates, no matter how many specialists are available.
