Human Engineering Laboratory Battalion Artillery Tests (HELBAT)

The Human Engineering Laboratory (HEL) has begun to develop the information through a series of field experiments superimposed onto Operational Readiness Tests (ORT) which Army units must undergo each year. Two of these field experiments, under the title of Human Engineering Laboratory Battalion Artillery Test (HELBAT), have already been completed and a third HELBAT has just been conducted. The artillery studies are scaled to battalion size. The battalion is the Artillery's basic operational unit and thus provides the greatest realism for operational study.
