Some officers in the 101st thought a 75mm pack howitzer could not knock out a German tank. The grunts ignored the naysayers and did it anyway

On Christmas morning '44 the 463rd Parachute Field Artillery Battalion were dug in northwest of Bastogne.

A German armored assault force helped out by showing up to provide tanks to submit for testing, with direct fire, at short range. 

The battalion claimed eight tanks destroyed, though only two could be confirmed at the time and other units shared the fight. Of the eighteen that began the assault, none survived the day. 

The 463rd received the Presidential Unit Citation for its work at Bastogne.
