Supreme Command Detachment 0CP

An ASTRA MILITARUM Detachment is one that only includes models with the ASTRA MILITARUM keyword (excluding models with the AGENT OF THE IMPERIUM or UNALIGNED keywords). 

- If Every unit in an ASTRA MILITARUM Detachment has the MILITARUM TEMPESTUS, OFFICIO PREFECTUS and/or MILITARUM AUXILLA keywords, TEMPESTUS SCIONS units in that Detachment have the Troops Battlefield Role, instead of Elites

- Troops units in ASTRA MILITARUM Detachments gain the Objective Secured ability (this ability is described in the Warhammer 40,000 Core Book).

If, in your movement phase, an OFFICER from your army disembarks from a TRANSPORT model, after that OFFICER's unit has been set up it can issue Orders as if it were your Command phase. However, when doing so, the Regimental Tactics ability does not apply, even if every model from your army has the ASTRA MILITARUM keyword. Note that an OFFICER model cannot issue Orders in this when disembarking from a destroyed TRANSPORT model.
