The enemy didn't know of the Dark Angels approach, they sat unprepared while the scouts worked their way into positions and silently directed their brothers. Without warning a squadron of Land Speeders swooped in raining death, Assault Marines fell from the sky, Scout snipers opened fire and all hell broke lose! Death from above :)

Close combat crazyiness! The Librarian would accompany the Assault Squad deep striking, making one big nasty unit that will have the enemy running in fear (weaken resolve rules!). The Scout snipers will pin units and deal with any high toughness targets (Wraithlords for example), while the close combat Scouts will use the terrain to advance and clean up any stragglers. The Land Speeders would make hit and run attacks on infantry and LIGHT armour.
