150222nd

The 150222nd is a fictional or placeholder designation used in science fiction, fantasy, and worldbuilding contexts to refer to a military or paramilitary unit. There is no record of a real-world organization formally employing this exact name.

The designation combines a large numeric sequence with an ordinal suffix, a convention often used in fiction to imply historical depth, organizational scale, or a lineage dating back many generations. Because it is not tied to a specific real entity, the 150222nd is interpreted differently across works and by worldbuilders.

In most fictional contexts, the 150222nd is depicted as a sizeable combat formation, frequently a mechanized infantry regiment or a spacefaring combat unit. Its exact composition, doctrine, and insignia vary by author, ranging from frontline regimental fleets to planetary defense forces. The unit is sometimes given a ceremonial lineage, distinctive emblems, or mottos, though these details are not canonical and are defined anew in each story or game.

As a common placeholder in fiction and worldbuilding, the 150222nd serves to illustrate how large numeric designations function within military hierarchies. It is not standardized, and there is no universal canon. Readers and players should consult the specific work for definitive characteristics.
