The Chapter Sigma are heavily influenced by the Codex Mathematika, which prioritises the maximisation of success. They employ a unique form of punishment, in the form of censure bands. Following 10 years of service in Chapter Sigma, a marine is judged to have sufficient experience to make appropriate judgement, and will receive three censure bands. Should the marine make a grievous mistake which threatens the safety of his brothers, his chapter or the Codex, he will be stripped of one band. Once a marine loses all of their bands, they are punished in an ultimate, irreversible way, the removal of their chest Progenoid, mirroring the original removal of Progenoids at the end of the Heresy. This is considered the ultimate shame by members of the Chapter Sigma and the third-censured will usually join a Censure Company, where they undertake risky and suicidal missions that may result in the total loss of gene-seed of their other uncensured brothers.

The Chapter Sigma also greatly despises the hero worship of specific marines. Upon death, the deeds of each space marine is added anonymously to the Hall of Deeds aboard the flagship Summate Infinitium, a chronicle of the sum of successes and failures of the chapter.
