Editing Warhammer 40,000/10th Edition Tactics/Space Marines (section)

====Special Rules====
*'''Combat Doctrines:''' At the start of your command phase, you can pick one of these to apply to all {{W40Kkeyword|adeptus astartes}} units in your army until the start of your next Command Phase, and each can only be picked 1/battle.
**'''Devastator Doctrine:''' Your army can always shoot after advancing, which is actually best on ''non-heavy'' weapons that lose nothing from Advancing rather than Remaining Stationary, meaning this buffs your Devastator Squads and the like ''least''.  Because GW is bad at rules, this ''doesn't'' add the ''Assault'' USR to all of your guns (instead applying the definition of it directly to every gun).
**'''Tactical Doctrine:''' Your army can shoot and charge after falling back, which primarily buffs units with {{W40Kkeyword|fly}} because they're better at falling back.
**'''Assault Doctrine:''' Your army can charge after advancing.
