From the description:
The Alpha Mare Legion had not one, but two Ponyarchs, Inkie and Blinkie Pie, but only together did they serve as a full Ponyarch. It was said they shared the same soul, whereas one was the brain, and the other one the brawn. Blinkie was the figurehead of the legion while Inkie acted in the shadows as second-in-command of the Legion. The existence of the two Ponyarchs is known only to the members of the Legion itself, and was a well-kept secret even from the other Legions.
Blinkie believed that secrecy, adaptability and fluidity brought military success, and taught her Legion to apply all such military techniques to both their training and their operations. The Legion’s victories in the Great Crusade all feature some form of subterfuge, misdirection or rapid, unexpected movement. Such victories required great skill and dedication to achieve, and the Alpha Mare Legion quickly became an insular and proud military organization. It was this martial pride and unusual philosophy that led to a number of clashes and fights with members of the other Space Mareine Legions, particularly against their rivals the Imperial Fillies on several instances.
After Blinkie’s’ disagreements with Twilightover the dishonourable ways of the Alpha Mare Legion’s chosen methods of warfare, the Alpha Mare Legion threw themselves even further into their preferred method of operations, largely cutting themselves off from standard Imperial military practices and orchestrating greater and greater victorious examples of their approach to the Great Crusade, even when more conventional attacks would have been more efficient. The most notorious example of this took place on the world of Galloping Prime, where the Alpha Mare Legion, instead of taking the opportunity to capture the planetary capital city and thus force the world’s surrender, allowed the enemy to dig in and defend it so that they could then expertly take the defending forces apart in a number of different ways. After a week of suffering seemingly random mishaps and deadly sabotage as well as brutal ambushes, the defenders were forced to capitulate, having taken 90% casualties. When asked why the Legion had not taken the simpler strategy, Blinkie is reported to have replied that they avoided it as “it would have been too easy.” This campaign brought Blinkie censure from almost all of her fellow Ponyarchs; Twilight in particular raged at Blinkie’s conduct of the war, labeling the drawn-out operation as “a waste of the Empress’s bolt shells.” Only the Warmaster Luna, always impressed by Blinkie and her work, praised the Alpha Mare Legion’s skill.
As a Legion who survived and prospered on subtetly and stealth operations, having the newest and most effective equipment was a must. And Blinkie, with her amazing intellect, regulary created new and better equipment. Much to Inkie’s delight, who always loved trying out the new gadgets supplied by her sister!
Which as a result also lead to the Alpha Mare Legion being the most high tech Legion out of them all.
(And secretly Loyalist, lol.)
