More than 4,400 service members from 45 units representing 15 states, which includes soldiers from five allied nations from the United Kingdom, Denmark, Canada, Suriname and Germany have arrived at the Black Hills of South Dakota and Camp Guernsey, Wyoming.

The two week training exercise known as Golden Coyote, marks it's 30th year as soldiers train in engineering, simulated military operations, humanitarian missions, and other skill-enhancing drills.

The benefit to such a large-scale operation is soldiers with different training to work together and perform a successful operation in the most critical of times.

Among those in training are 250 paratroopers from the Texas Army National Guard’s 1st Battalion, 143rd Infantry Regiment (Airborne), who exited out of C-130 aircraft and landed to secure a drop zone as they infiltrated Golden Coyote.

Hosted by the South Dakota Army National Guard and held in the Black Hills National Forest and Custer State Park – the two-week exercise concludes on June 21st.
