==Outlook and Training==

Although the Custodes were among the first modified warriors to be created by the Emperor, they were never intended to be part of a conquering army; such a role was to be filled by the latter Astartes armies. This is revealed both in their mindset and training, where the Custodes do not fight as brothers and sisters and as a greater whole but rather as individual warriors. This is in stark contrast to Space Marines, who employ a high degree of teamwork and collective tactics in battle. At least some Astartes look down on the Custodes for these tactics, and it may be that this was deliberately designed so that they shared a bond with none but the Emperor himself.{{Fn|6a}} Whatever the truth, the Custodians are undoubtedly fanatically loyal to the Emperor and will carry out any task he demands, regardless of how brutal or suicidal it may be.{{Fn|19}}

Some Custodians are known to practice [[yothagna]], a form of meditative exercise, in their quarters during their personal time. Some yothagna techniques involve sitting cross-legged on a rug while practicing a series of breathing patterns and controlled body movements.{{Fn|36a}}

===Martial Ka'tah Fighting Styles===

Custodes are taught a series of powerful stances known as '''Martial Ka'tahs'''. These fighting styles can be adopted in unison by entire [[Shield Host]]s{{Fn|39}}, and each has a preferred Ka'tah they use in battle{{Fn|40}}. By doing so, the Shield Hosts bring centuries of training to bear with violent precision.{{Fn|39}}
