SetDef citizens have a variety of accents, though they seem to mainly be German and Russian, with some American, British and Australian accents. SetDef soldiers also have a rather unusual way of talking, often utilising quite formal speech, which can sometimes be unusually verbose, even during casual conversation. For example, rather than simply saying "I agree", they may say "confirmed" or "concurred", while also referring to UNSA cultural ideals as "cultural doctrine". Slang also tends to be lacking, aside from the use of the term "blue" to refer the the UNSA. SDF soldiers often refer to each other as "kindred".
