Four U.S. Army logisticians will be on a special mission this month: competing in the 2016 Olympics in Rio de Janeiro. All will be trying to earn a special service medal: an Olympic Gold. Two are motor transport operators: Sgt. Nathan Schrimsher, a modern pentathlete, and Spc. Leonard Korir, a 10,000-meter runner. Watercraft engineer Spc. Daniel Lowe competes in the air rifle and three-position prone rifle competitions; and water treatment Spc. Paul Chelimo runs the 5,000-meter.The four logisticians are among 13 Soldiers who will be joining Gold Medalists Michael Phelps, Kevin Durant, and Katie Ledecky among others on the 555-person American Olympic roster. And they follow in the path of military legends. Soldiers have competed in Olympic Games since 1896. In the 1912 games in Stockholm, then-2nd Lt. George S. Patton Jr. finished fifth in the inaugural running of the Modern Pentathlon, and went on to become one of the greatest leaders in military history. Each of these Soldier-athletes represent the Army's best. They're ready, and they have the entire logistics community ready to root them on. Here is information about each one, from the Army's World Class Athlete Program.Schedule of Events:Specialist Paul Chelimo Specialty: Water Treatment Specialist Event: 5,000 meter Schedule: August 17, 10:05 am EST, Round 1 August 20, 9:30 pm EST, FinalA native of Iten, Kenya, Chelimo came to America in 2010, and ran for the University of North Carolina, Greensboro.
