Editing Warhammer 40,000/7th 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.

*'''Tau Empire''': What are the Tau? Ungodly shooting power. You can give them infantry that doesn't suck in CQC.  Also, crisis suits are just like attack bikes, except better in every way. They used to be a lot better in 6E when they were Battle Brothers, but nowadays a lot of their utility is lost.  If they end up too close to the Tau, they'll be doing nothing, which will be costly. It pays to remember, though - Tau don't have to be a static gunline. Battlesuits - all of them except R'Varnas and Broadsides - are jet pack infantry. That means they can Deep Strike and they can seriously haul heinie. Play your cards right, especially with a Farsight Enclaves detachment, and OEO will never be a problem. Use fusion-armed crisis suits or ion/fusion Riptides to destroy a Land Raider then jump them clear just in time for your assault termies to smash the hell out of whatever was inside.
