Army trucks pull field guns across a countryside field in exercises.
Hertfield Artillery Training.
Several open cars carrying military officers drive across a countryside field. They are followed by trucks pulling field guns. Several shots of the trucks and cars driving about the field. Looks like military exercises.
The trucks finally come to a halt, soldiers jump out and put the field guns into position. Then shots of the trucks pulling the guns across the field again. Closer shots of the soldiers hooking and unhooking the guns from the trucks. Soldiers load the guns and fire them.
