Description
Summary:This work represents field measurements of performance times for the crew of an M198 howitzer. The M198 is a towed, 155mm artillery piece, manned by a 10-member US Marine crew for this exercise. Baseline times in battle dress uniform and degraded times in full nuclear and chemical protective gear (MOPP4) are included. Reported times consist of emplacement time, displacement time, time to first round (TTFR), and time between rounds (TBR) for three fire mission types. Baseline times for TTFR and TBR show a decrease (improvement) with repetition number during a day's fire missions, indicating a significant practice or warm-up effect. Times for TTFR and TBR show a significant increase (degradation) when the crew is at MOPP4. The performance degradation worsens with mission repetition (increasing time-in-MOPP4). These measurements are part of the ongoing effort of DNA's Radiation Risk/Safety program to support quantification of military performance degradation in an NBC environment. Sponsored in part by contract DNA001-90-C-0164. Prepared in cooperation with ARES Corp., Arlington, VA.
