M82 also can be used to defeat enemy snipers or criminals from standoff range or when targets are behind the cover, but the anti-personnel work is not a major application for Barrett M82 (or any other.50BMG rifle, for that matter).
The latest derivative of the M82 family is the M82A1M rifle, adopted by USMC as the M82A3 SASR and bought in significant numbers.
M82 rifles are often equipped with Leupold M series 10X telescope sights.

 M82 Press Release: Space.com Article
The rapid-fire star birth in M82 was triggered by a collision with another galaxy, and the tremendous activity fuels a "cosmic hurricane is travelling at more than a million miles an hour [447 kilometers per second] into intergalactic space," said Linda Smith of the University College London.
But M82 is noted for its "superwinds," as astronomers call the bipolar outflows.
M82 is about 10 million light-years away, which is relatively close in space and time.

In the infrared light, M82 is the brightest galaxy in the sky; it exhibits a so-called infrared excess (it is much brighter at infrared wavelengths than in the visible part of the spectrum).
The visual appearance is that of a silvery sliver, as John Mallas decribed it.
M82 belongs to those few Messier objects which have been assigned a Herschel number, H IV.79, while William Herschel usually carefully avoided to give his numbers to Messier objects.

 M82 Press Release: 21/5/04
M82 – which astronomers call a “starburst galaxy” - is located at a distance of a bit more than 10 million light years from our own Milky Way.
M82 sits in a galaxy group that includes M81, M82, NGC 3077 and NGC 2976.
M82 is classified as a peculiar galaxy because it does not fit into this standard classification scheme.

 M82 Exploding Galaxy?
M82 is the 82nd object in Charles Messier's 1784 catalogue of faint nebulae.
If the quasars are at the distance of M82 (3.3 Mpc), then their separation is on the order of 3.4 kpc and the distance from the nucleus of M82 is approximately 8 kpc (Our Sun is 8.5 kpc from the Milky Way nucleus).
Because of the nearness to the disturbed galaxy M82, if the quasars were ejected from it, then an explanation should exist for their low velocity dispersion (nearly identical redshift velocities), And of course the nature of the ejection mechanism or explosion would have to be explained.

M82 is also the closest starburst galaxy to the Milky Way.
One compelling scenerio is that M82 may have been a more massive spiral galaxy at one time.
The last encounter with M81 may have left M82 stripped of stars and gas with its remaining bulge and nuclear disk considerably truncated as it appears today.

 Messier Object 82
M82 was discovered on December 31, 1774 by Johann Elert Bode together with M81; he described it as a "nebulous patch", about 0.75 deg away from M81, which "is very pale and of elongated shape," and cataloged it as No. 18 in his catalog.
M82 belongs to those few Messier objects which have been assigned a Herschel number, H IV.79, based on an observation of September 30, 1802, while William Herschel usually carefully avoided to give his numbers to Messier objects.
William Parsons, the Third Earl of Rosse, was the first to remark on the dark dust lanes and patches visible in the central part of M82.

M82 has an angular size of 9 x 4 arcminutes and has very high surface brightness.
The high surface brightness is due to the very high star formation rate currently operative in M82.
The interaction of this star formation pattern and the peculiar distribution of dust in M82 gives rise to its peculiar appearance and its misnomer label as an "exploding galaxy".

 Starburst eye of a galaxy produces a cosmic shower (May 21, 2004)
The starburst galaxy M82 is one of the most studied objects in the sky.
Known as a starburst galaxy for the intense, bright clusters of young stars at its heart, M82 is also characterized by massive jets of hot gas -- tens of thousands of light years long -- that blast into intergalactic space perpendicular to the starry plane of the galaxy.
The emphasis of the new work, according to UW-Madison astronomer Jay Gallagher, was on the powerful high-temperature winds of M82 and using the Hubble and WIYN observations in combination to view the galaxy in a new way.

 Messier Object 82
M82 (Le fleuron des galaxies pour beaucoup d'observateurs de l'hémisphère nord) forme une très remarquable paire physique avec sa voisine M81 et représente le prototype d'une galaxie irrégulière du second type, c'est à dire ayant un "disque" irrégulier.
M82 a été découverte le 31 Décembre 1774 par Johann Elert Bode en même temps que M81 ; il la décrivit comme "une tache nébuleuse", à 0,75° environ de M81, "très pâle et de forme allongée" et l'inclut dans sa liste sous le No 18.
M82 fait partie des quelques objets de Messier, peu nombreux, qui ont aussi un numéro Herschel, H IV.79, alors que, habituellement, William Herschel évitait soigneusement de leur donner sa propre numérotation.

 Multiwavelength Messier 82 - Peculiar Starburst Galaxy
M82 is classified as an irregular galaxy, but its unusual appearance has led many to describe it as a prototypical example of a peculiar galaxy.
It is also one of the brightest infrared and radio sources in the celestial sky, a result of galaxy-wide bursts of star formation.
But it appears to be surrounded by a fuzzy halo, and wisps of optical emission are evident along a line that is roughly perpendicular to the major axis of the galaxy.
