Posted to the official Space Force website:
The U.S. Space Force is looking for feedback from U.S. military space professionals on what Space Force members should be called – similar to how the Air Force refers to its members as ‘Airmen’ or the Army refers to its members as ‘Soldiers’.
Given the significance a name has to the identity and culture of an organization, the Space Force is taking a deliberate approach to ensure Space Force member titles and ranks appropriately convey the nature of the newest Armed Forces branch and the domain in which it operates.
Toward that end, Space Force officials are soliciting ideas related to Space Force ranks, names for operational units and what Space Force members should be called collectively. They are especially interested in soliciting ideas from those currently assigned to the U.S. Space Force or those who expect to be members of the Space Force in the future.
Officials emphasized several guidelines respondents must consider when submitting ideas. For example, proposals must be gender-neutral, distinctive and should emphasize a future-oriented military force. In addition, submissions cannot violate copyrights, infringe on trademarks or other intellectual property rights, or be proprietary. Any submission falling into those categories will not be considered. Submissions must also be in good taste.
