America’s special operations units have seen a dramatic uptick in the missions sets they’ve been tasked with throughout nearly two straight decades of the War on Terror, but despite some overlap in combat operations, each specialized unit has a specific area of expertise to draw from. The Navy SEALs, as most could assume from their name alone, specialize in water-born operations, and as such, they have a long list of specialized tools in their team rooms for just that sort of work.

While SEALs are often seen in Defense Department footage fast roping down onto the deck of ships from aloft helicopters, the reality of modern combat dictates that such an insertion isn’t always possible. That’s why SEALs don’t only employ quiet, stealthy watercraft — they’ve also got some loud, angry, souped up boats that are perfect for rapidly closing with enemy vessels. The problem is, once you’ve whipped your supercharged jet ski up alongside an oil tanker full of terrorists… how do you get on board? That’s where the incredible tech in the REBS Magnetic Climbing System comes in.

The REBS system is made up of four high-powered magnetic grips, with two designed to capture feet and two intended for use with your hands. The lever operated system is entirely waterproof and dive capable, meaning SEALs and other combat divers can actually engage the system from beneath the waterline to begin their climb up the ship’s hull to the deck.
