AM General, the military contractor that developed the original Hummer teamed up with Jeep on the Gladiator Extreme Military-Grade Truck (XMT), a lightweight off-roader that could bring Jeep back to battlefields for America for the first time in 20 years. Depends on how many, if any, the U.S. military orders. Based on the current model Wrangler, the Gladiator pickup features a battle-ready design but few tech specs have been released except for the mil-spec model, there’s a 3.0-liter turbodiesel V6 under the hood.
