locked up
adj.— «Having survived the “Aladdin” test, Pvt. Kyle Brower, 18 years old and just a few months removed from civilian life, was able to stand still and stare into the middle distance during his first dignified transfer last week. He was able to carry the coffin while remaining, as the soldiers call it, “locked up”—both physically and emotionally. If his thoughts wandered to the soldier inside, how he or she died, he was able to snap back.» —“‘They’re a fallen soldier, and they deserve the highest respect and honor we can give’” by Christian Davenport Chicago Tribune (Illinois) Apr. 6, 2009.
