Making Waves In and Out of the Pool; Why Two Marine Raiders Started Their Own Sports League and Training Program After Serving


In 2009, United States Marine Prime Hall, who had passed the three-week Marine Corps Water Survival School in which less than 50 percent of enrollees complete, was an instructor to certify combat water-safety swimmers. That’s how, in 2010, he met and trained Don Tran at Camp Pendleton in California. From that point on, Hall and Tran spent nearly a decade learning to remain calm in any and all dangerous underwater situations.

Two Former Marines Captain a Game Changer in Underwater Athletics


A new water sport attracting active military members and veterans, MMA fighters, CrossFit enthusiasts, surfers, lifeguards, freedivers, former collegiate swimmers and water-polo players got its start here in California.

Underwater torpedo tasks two teams of five players with placing a torpedo-shaped toy into a kid’s hockey net anchored to the bottom of a 13-14 foot pool. Sound easy? It’s not. All the action happens underwater, requiring swimming skill and breathing endurance. Pop above the surface with the torpedo in hand and that’s a penalty.

Welcome to the Underwater Thunderdome: Torpedonull Gravity: Underwater Torpedo League


Two teams enter, one team leaves—victoriously, that is, as this Marine Raider-created sport isn’t one played to the death, though it can be just as cutthroat as any game found it in a Mad Max movie.

With its roots in water polo and underwater football, the game’s original design was to create a training tool to help develop underwater confidence and the skill to remain calm.

In order to play the game successfully, you have to have a high level of athletic skill, stamina and calm…

A Group of Marine Raiders Created an Underwater Sport for Training — and It’s Gaining Traction


“In training sometimes you get these instructors that are strictly sink or swim, and there’s definitely times you need that, but in pool training — a lot of people have had bad experiences in the pool — it’s best to have a ‘calm breeds calm’ training approach,” Prime Hall, a former Marine Raider and the game’s creator, told Task & Purpose.

The genesis for the sport began simply enough: Tossing a torpedo underwater and watching it zip across the pool gives you something else to focus on. You’re less concerned with your air, and more interested in making precise passes — one, two, five, ten, and so on.

Us Marine Raiders Created Extreme Underwater Sport


It looks like a submerged version of the Thunder Dome, or a very rowdy game of water polo, but with more moto-tats. Pioneered by some of America’s most elite warfighters, it requires extreme stamina, athleticism, and confidence. And it’s gaining traction far beyond the special operations community where it began.

Called Underwater Torpedo, the sport was developed by a group of Marine Raiders as a swim-training tool to help them remain calm underwater. But if you’ve watched any of the gameplay footage, or seen the photos, it’s hard to imagine this has a calming effect on anyone…

USD Splashes in UTL Debut


Club sports at the college level offer a wide variety of options for students. Organizations range from club baseball and softball, to basketball and even lacrosse. The Underwater Torpedo League (UTL), however, offers a complete departure from the traditional intercollegiate athletic landscape. Rooted in games developed in U.S. Marine special forces training, the UTL resembles a cross between water polo and rugby.

Teams of five, donning only a swimsuit and goggles, face off and attempt to move a small torpedo that is not unlike a child’s pool toy into the opposing team’s net at the bottom of the pool to score points. Any movement with the torpedo must occur while the player is underwater, and perhaps more importantly, any contact in an attempt to steal the torpedo while underwater is legal. Despite the inherently rough nature of the sport, the UTL prides itself on being inclusive of players of all skill and experience levels…
