Dalahar laughed, a strange sound that was robbed of any levity by the vox distortion. "I'm not entirely sure. The Alpha legion aren't like us in the word bearers or any other legion for that matter. They don't have a defining trait or tactic or preference of war. Mutable. That's how I'd describe them. Their tactics change every battle, every theatre, every skirmish. They strike with exactly what is needed. The interesting thing about them is the make extensive use of agents, for want of a better term. Humans mostly, trained to interact with certain factors where delicacy is required and astartes lack that trait. The alpha legion can fight a war purely with misdirection. Intelligence gathering, intentional leaks, false flag operations, political subterfuge, radical insurrection, double agents. Fighting the alpha legion is like fighting a myth, you never know what you come up against each time, most often foes find themselves beaten before they commit to battle without even realising the depth of the plots and strategies employed against them. The other legions see this as cowardly or wrong but I can see its merit"
