Editing Warhammer 40,000/6th Edition Tactics/Space Marines (section)

===Desperate Allies===

*'''Dark Eldar''': They are faster than you, so use that. A good strategy with them are using them as skirmishers and go against one unit at once. Kabalites are good versus infantry and monsters or launch Wyches against vehicles. Do not invest in Haemonculi's minions, you have better stuff. Remember keep them far from your units. The marines will likely survive one turn stopped and useless, the DE don't.

*'''Necrons''': They're the anvil. You're the hammer. Let the undead robots take the shit, because they can handle it. You can deep strike later to win the day. Also useful when there are many high-armor (13+) vehicles in the field.

*'''Orks''': Use them as a first and expendable wave to tarpit and soften the enemy or silence their biggest cannons by assaulting them (or both), so you can later choose better your attacks. But remember that you have to begin the marine offensive when every one of the orks are dead, as the "One eye open" rule can ruin even the best plan.
