Marines with Medium Tiltrotor Squadron 261 (Reinforced) and Light Armored Reconnaissance Platoon of Battalion Landing Team 1st Battalion, 2nd Marine Regiment, both with the 24th Marine Expeditionary Unit, refuel a Light Armored Vehicle 25 using the tactical bulk fuel delivery system May 9, 2012 to prepare for Exercise Eager Lion 12. The tactical bulk fuel delivery system is a large fuel bladder installed inside the hull of a CH-53 Super Stallion helicopter. This system increases the range and flexibility of tactical refueling allowing Marines to refuel anywhere they can land a helicopter. During Eager Lion 12 the 24th MEU will participate in a variety of training exercises with partnered nations at different locations throughout the country to increase interoperability and learn about other countries' militaries. Eager Lion 12 is a recurring exercise designed to strengthen military-to-military relationships through a joint, whole-of-government, multinational approach to future complex national security challenges. The 24th MEU, partnered with the Iwo Jima Amphibious Ready Group, is currently deployed to the U.S. Central Command area of operations as a theater-reserve and crisis-response force capable of a variety of missions from full-scale combat operations to humanitarian assistance and disaster relief.
