 | Bore cleaning is an essential part of gun barrel maintenance. The technical manual for the Abrams tank gun barrel calls for bore cleaning to occur after every firing exercise. Standard practice at a military proving ground, such as Aberdeen Proving Ground, MD, is to clean the barrel after every firing program, perhaps 5 to 10 cleanings per barrel per year, 250 total cleanings per year. The degree to which a ... |

| Military vehicles can be extremely noisy working environments. Noise impairs vehicle crews in various ways, for instance through its effect on speech intelligibility and the audibility of other useful sounds. Exposure to high noise levels may, in the long run, also cause an irreversible hearing loss.
