The top teams dominated the famously tough competition all weekend, leading the pack of 50 teams.

Just 23 teams made it to the final day of competition.

The annual David E. Grange Jr. Best Ranger Competition is a storied three-day event that pits two-man teams against each other in back-to-back events. The winning duo will earn the title of Best Ranger.

Competitors, who must be graduates of the Army Ranger School, are put through events that test their physical conditioning, Ranger skills and team strategies. The events are back-to-back and around the clock for 60 hours, allowing little time for rest and meals.

Events this weekend includes weapons firing, extended road marches, day and night land navigation courses, Ranger skills and parachute jumps. All events are timed, and competitors score points for each completed event. Both team members must complete each task.

The Best Ranger Competition was established in 1982 and has been compared to Ironman and Eco-Challenge competitions.

A formal awards ceremony will take place at 10 a.m. Monday at McGinnis-Wickam Hall in Fort Benning's Marshall Auditorium.
