The second sense referring jocularly to the readiness level that was needed in "rapid deployment" units -- troops who would need to activate/deploy in as little as 2 hours if the Russians really were coming (Cold War)
COMMON/CONTEMPORARY: "Geez, look at Private Smith: hair buzz-cut, uniform perfectly pressed, patches and pins immaculate, leather polished to a mirror-brightness. Such a pity the loser has no skills whatsoever. STRAC jerk."
