As a preliminary test of the feasibility of employing in roles of tracer an ammunition which flashed upon impact, five infantrymen reported after each of 60 rounds what type of ammunition was fired and which of four targets from 500-740 meters was engaged. Each subject then engaged a target at 580 meters with an M60 machinegun firing up to 100 rounds of M62 tracer and an M1919A4 machinegun firing to 100 rounds of cal. 30 API ammunition. The test was conducted once in daylight and once in early evening. The API ammunition displayed no advantage over M62 tracer, and subjects unanimously stated they preferred standard tracer.
