One might wonder at the rank of 'sergeant' which in English (and hence the corrupted Galstandard West) originated from the latin word for 'servant' and through the passage of centuries went from meaning 'soldier-servant of a knight' to meaning 'I am your momma, your poppa, and your shoulder to die on.'
In the Kssthrata tongue the word has a different (albeit rather parallel) history, and stems from the tooth-related word "serrator" and the word "gentle(man)." Literally, the rank of sergeant among the Kssthrata is the leader of the 'serrator' troops, or 'gent responsible for serrating our enemies.'
A kindly gent indeed.
