As usual per Selkie-custom, women are included in all positions and occupations of the SDF, as neither sword, nor plow, and least of all rifle care, if the hand touching them is strong or soft. This had been the case since the foundation of the SDF and even before.


The SDF, officers and men alike, salute by balling their fists, tapping their chests twice where their heart is.
