The 75th Ranger Regiment (United States Army Rangers) uses Sua Sponte as their regimental motto, referring to the Rangers' ability to accomplish tasks with little to no prompting and to recognize that a Ranger volunteers three times: for the U.S. Army, Airborne School, and service in the 75th Ranger Regiment.[14]

The Ash Street Shootout of 1989.

Sgt. Bill Foulk was an Army Ranger at Fort Lewis, Washington, when he purchased a cheap house in a rough Tacoma neighborhood as an investment in 1989.

Foulk grew concerned that a house on Ash Street, his block, was infested with gang activity. He purchased his own house for $10,000 ($20,875 in 2019 dollars), with the idea that property values would rise.

He began to videotape the people who visited the suspected drug house. He wasn't wrong. The occupants were members of the Crips, the violent street gang that was spreading from California to Washington in search of new markets for drugs.
