undersecretary – One word, lowercase unless preceding a name in a title.
Uniform Code of Military Justice – Spell out on first reference, then use UCMJ.
United States – Refers to the 50 states and the District of Columbia. Use the abbreviation U.S. in texts and US in headlines.
URL – Acceptable in all references to Uniform Resource Locator. When the URL doesn't fit on one line, break into two or more lines without a hyphen or other punctuation. In printed or downloaded documents, such as fact sheets, information cards, trifolds and other PDFs, use the complete URL including https:// or http://. The only exception to this rule is the URL for the Military OneSource website, which can be written in any of the following ways for printed or downloaded documents:
- Uppercase and lowercase letters — www.MilitaryOneSource.mil
- All lowercase letters — www.militaryonesource.mil
- Without www — MilitaryOneSource.mil or militaryonesource.mil
For printed or downloaded documents, always hyperlink the URL so it can be used for both web and print purposes.
Do not spell out URLs in emails where the URLs will be hyperlinked. Hyperlink a word or phrase in the paragraph similar to content in Military OneSource articles, as the URL will display after the hyperlinked text once the email has been sent. For example: "Use Plan My Move to organize your next move" will appear as "Use Plan My Move https://planmymove.militaryonesource.mil/ to organize your next move" once the email has been sent.
