the upper mobile turret was then bore-sighted in a known azimuth<br />
and a marker placed on this moving turret on that heading. If the<br />
North Star was sighted, then the marker would be placed on true<br />
north. As long as the half-track was in a stationary position, the turret<br />
could be rotated and the azimuth could be read like a compass. <strong>The</strong><br />
elevation of the guns was obtained by use of a gunner’s quadrant<br />
placed on two fixed points on one of the 50-caliber guns. As the gun<br />
was elevated, a bubble level measured the mils of elevation at which<br />
the guns were to be fired. <strong>The</strong> troops had firing tables that indicated<br />
the elevation in mils required for the trajectory to reach any distance<br />
within range of the guns. <strong>Dan</strong> was issued maps of the terrain with field<br />
artillery forward-observer positions marked, and with this the platoon<br />
was ready to start firing. <strong>Dan</strong> set up the fire direction center (FDC) in<br />
his bunker on a hill above the field artillery positions.<br />
About 10 o’clock that first night, one of the forward observers called<br />
him and gave a fire mission on enemy moving on a distant hill. <strong>Dan</strong><br />
gave settings to four half-tracks to fire 100 rounds from two guns on<br />
each vehicle. When all was ready, he gave the commence firing order<br />
and eight 50-caliber guns cut loose, spraying the target with exploding<br />
A quad-50 emplacement. Enemy trenches are on hill to far right.<br />
