Step-by-step explanation:
The tour of duty length for active duty personnel to be an EO volunteer varies depending on the branch of the military and specific program. In the U.S. Army, for example, the tour of duty is typically between two to three years. However, this can change based on the needs of the military and the individual's qualifications.
For the U.S. Air Force, the tour length is usually four years. Again, this may differ based on the specific program and circumstances. Other branches of the military, such as the Navy and Marines, may have different tour lengths for EO volunteers.
It's important to note that these lengths are general guidelines and can be subject to change. It's best to consult official military sources or recruiters for the most accurate and up-to-date information regarding tour of duty lengths for EO volunteers.
