Crimson Fists - Chapter Combat Doctrine: When the Crimson Fists Chapter was formed, Primarch Dorn granted Chapter Master Polux its membership from among the most recently initiated members of the Imperial Fists Legion. While these battle-brothers were thoroughly trained and loyal men, they were among the Legion's most levelheaded members. Because of this, the new Chapter Master was able to more effectively implement the teachings and new traditions of the Codex Astartes.With few exceptions, the Crimson Fists are very consistent with the Codex in terms of organisation and battlefield procedures. They usually follow the tactics presented in the Codex, efficiently making use of different standard units in the manner that sacred tome describes. Their training is broad and all encompassing, so that the Chapter can effectively counter opponents who use vastly different tactical approaches to battle. In this way, the Crimson Fists quickly adapt their tactics to defeat any who would oppose the will of the Imperium.While the Chapter has served throughout the galaxy, they have made the Loki Sector their primary base of operations for millennia. As the sector has been dominated by Orks since humanity first encountered the region, the Crimson Fists have engaged in countless wars with these savage xenos. Though they are not specifically devoted to overcoming these foes, the Chapter's battle-brothers are well versed in Ork psyche, physiology, and tactics. The near-constant supply of Ork warbands in the region makes this training necessary and profoundly useful. As this ability has become associated with the Chapter, the Adeptus Administratum and even the Inquisitorial Ordo Xenos have often requested assistance from the Crimson Fists when significant Ork forces gather throughout the Imperium.As successors to the Imperial Fists, the Chapter does show a marked competency with defensive engagements. The Chapter's Warp-capable vessels and Fortress-Monastery are all thoroughly defended. Even their first engagement as a Chapter after their Founding involved defending an Imperial colony on Uralek Prime from a substantial force of Eldar Exodites.During the nine thousand years of their Crusade, the Crimson Fists became skilled at combating many alien species, most notably the Orks. These skills have been valuable to the Inquisition, with many members of the Chapter serving terms with the Ordo Xenos' elite Deathwatch. Captain Octavius, an Imperial Fist seconded to the Deathwatch once commented that no other Chapter has provided as many Space Marines to the Deathwatch as the Crimson Fists. As a result, the Crimson Fists are among the most highly regarded xenos fighters in the Imperium. Captain Octavius also ruminated on the loyalty and sense of duty possessed by the Chapter and its Astartes. Despite their severe losses on Rynn's World, the Crimson Fists continue to second battle-brothers to the Deathwatch. In fact, no less than one quarter of Captain Octavius' own eight-man Kill-team were Crimson Fists.Though famed for their stubborn, intractable defensive actions, much like their progenitors, the Imperial Fists, after the Battle of Rynn's World, the sheer number of casualties suffered by the Crimson Fists has prevented the Chapter from fighting in the way prescribed by the Codex. Instead, Chapter Master Pedro Kantor has fielded his surviving Astartes as infiltrators and guerrilla troops, attacking specific, high-value targets in an attempt to minimise casualties as opposed to engaging enemies in open battle. This will change in the coming decades once the Crimson Fists begin to refill their depleted ranks.
