The words
Ammunition
Ammunition shortages restricted artillery support during the October 2 attack. The corps study records that planned fire against German batteries had to be reduced.

Booby Traps
Near Raffelsbrand in November, booby traps reinforced wire, mines and defended positions. The forest attack brought American infantry heavy losses and little progress.

Dragon's Teeth
Rows of concrete projections were intended to obstruct tanks. The Army history describes them as one element of defenses also exploiting rivers and difficult terrain.

Embrasure
An opening in a fortification for firing weapons.
The pillboxes’ firing openings mattered to both defenders and attackers. The corps study describes combat centered on these small apertures in the fortified positions.

Prum
Prüm was an important Eifel communications center. The September plan assigned it to American infantry, while armored troops farther south were directed toward Bitburg.

Siegfried Line
The West Wall comprised belts of fortifications along Germany’s western approaches. Its strength varied, with denser defenses around Aachen and weaker stretches elsewhere.

Stolberg
The Stolberg Corridor offered a relatively open route southeast of Aachen. River valleys, industry and nearby forests still complicated the American attempt to advance.
Ch. IV, pp. 67–68, the corridor and terrain · Army history: the Stolberg Corridor (opens a new tab)
Tank Ditch
Antitank ditches were intended to obstruct armored vehicles. In the XIX Corps assault area, the wartime study found them incomplete and limited in extent.
