Ultramarine blue and Air Force yellow are the Air Force colors. Blue alludes to the sky, the primary theater of Air Force operations. Yellow refers to the sun and the excellence required of Air Force personnel. The horseshoe symbolizes the foundation upon which the Squadron stands and the six nails refer to the last digit of its numerical designation. The strong horse rearing and reined by lightning bolts represents the unit's mission, mobility and speed of accomplishment. The collar with the wings signifies an Air Force support unit using heavy equipment. The emblem bears the national colors and the Air Force colors. The Latin motto, "IN PUGNA," translates in English to "IN THE FIGHT."
