Editing Tactics - Adeptus Arbites (9E) (section)

===Allies===
*'''Astra Militarum''': While Arbites have light infantry and expendable units covered by Penal Legions and Enforcer Cadres, they seriously lack psychic capability and heavy artillery. Their longest-ranged weapon is 48", and while a free vanguard move is nice, artillery always helps. Bring a Spearhead detachment, fill it with basilisks, and you now force your opponent to try to stop your Basilisks from killing your army now or try to stop your approaching Arbites from killing them later.
*'''Inquisition''': Given that Inquisition keep losing unit after unit each time GW chooses to update them, this is basically the only army built to work with the Holy Ordos instead of alongside them. Take a Valkyrie, throw in an Inquisitor, a Shock Team, kit them all out for melee, use the Inquisitorial Cooperation Stratagem and drop it on whatever you want to kill (short of a vehicle). Add a melee-Marshal for the re-rolls!
