Shield
The scarlet of the shield is for Field Artillery. The floating parachute with the cannon attached is symbolic of airborne functions of the organization.
Crest
The griffin is a fabulous animal half eagle and half lion. The eagle alludes to the organization having served with the 101st Airborne (Screaming Eagle) Division in World War II and the lion to England, where it underwent training and from whence it "took off" for its air assault drops on Normandy and the Netherlands. The trident refers to "Operation Neptune" which launched the invasion of Normandy symbolized by the fleur-de-lis, an emblem of France, impaled on the tines, and alludes to the Normandy air drop. The arrowhead and orange flames (orange is the Netherlands' national color) refers to the air drop on the Netherlands. The red and blue shield, suggested by the coat of arms of Bastogne, refers to the gallant defense of Bastogne, and has been "surrounded by" a border in allusion to the town being surrounded by the enemy and is white to simulate snow, the action having taken place during winter. The green mound refers to the Rhineland campaign and Southern Germany.
