Editing Warhammer 40,000/9th Edition Tactics/Space Marines (section)

====Imperium====
*'''Blood Angels:''' Blood Angels are very hit or miss. If you're playing a melee Marine faction, skirmish with them. White Scars in particular can practically instantly kill any Blood Angels unit with a squad of Vanguard Veterans on the charge. If you're playing more long range shooty, mow them down, might be difficult with the jump packs, but try anyway. If you're playing a bit of both, like Salamanders, feel free to just take the midpoints. Salamanders and Inner Circle Dark Angels in particular are incredibly strong against Blood Angels when it comes to contesting the mid points.
*'''Dark Angels:''' You beat these guys by playing the objectives. If you want to take potshots at them, do it. If you want to rush them with Vanguard Vets, have fun, but at the end of the day, they're slow and you're fast, or they're fast but have very little else going for them (in the case of Ravenwing). Just claim the objectives and stay calm.
*'''Space Wolves:''' These guys can intervene and are just, in general, incredibly strong. Very strong counter assault in particular. If you're playing melee, this is where you need to bring out some guns. Inceptors in particular are good at dealing with Space Wolves. Remember to Deny your opponents spells.
*'''Deathwatch:''' 
*'''Grey Knights:''' These guys have strong shooting and eternal deepstrike. Screen well, and use your higher efficiency units to deal with them.
*'''Imperial Guard:''' These guys have big guns and bad infantry. Kill the infantry with your infantry. Remember your marines have melee. Then use your amazing anti tank to finish off their no-invuln vehicles.
*'''Adeptus Mechanicus:''' Stay out of sight and grab objectives when you can. If you have more firepower or some consistent way to kill them, do that. Games with the Adeptus Mechanicus quickly devolve into murder.
*'''Adeptus Ministorum:'''
*'''Adeptus Custodes:''' Take the objectives and out efficiency the infantry. Shoot the vehicles with everything you have.
*'''Imperial Knights:''' Anti-tank them out. If you can deal with one knight, you can deal with the rest.
