Description: For each HQ choice in a Detachment (not including other Meks) you may include a single Mek chosen from this datasheet. These selections do not use up Force Organisation slots. Before the battle, immediately after determining Warlord Traits, any Mek that is not already part of another unit must, if possible, be assigned to any unit with the Infantry or Artillery type in their Detachment; a Mek cannot leave his unit and is treated as part of it for the entire battle for all rules purposes.
