See squads below for details on profiles and points cost.

Weapons & Options: The standard weapons and options available to the squad type chosen are available to the Command squad.
Characters: The standard characters available to the squad type chosen are available to the Command squad. In addition, one model may be upgraded to an Apothecary, one model may be upgraded to a Techmarine and one model may be upgraded to a Standard Bearer. Any of these characters may take equipment from the Dark Angels Armoury.

Errata — Chapter Approved: Codex: Dark Angels Q&A (v2.0): For a Land Speeder Command squad, the only weapon "option" available to the squad's speeders is the assault cannon upgrade allowed for ordinary speeders (see WD266 for the options) — the rest of the wargear list isn't relevant, since the speeders are vehicles.
