Also "Diosuno" is the first word of a Spanish prayer meaning that there is only one God inside a Trinity of three persons... http://www.franciscanos.org/oracion/rnb23.html
RTAD -- Research Tactical Arms Development (need to be confirmed by the army)
Worn by the US MilGroup "Advisors" (U.S. Army Special Forces) in El Salvador. The Riad is probably an acronym.

The technical term for this Patch seems to be a Shoulder Scroll.
