M4 assault musket, also call it carabin, this is the United States the improvement of M16A2 of musket of the 2nd acting assault edition, gun body shorter, weight lighter, performance is steadier.
Company of Ke Er spy can design M4, was to answer the requirement of the Marine Corps, they need a maneuverability more the musket making type of the gun. On the other hand, right now M16 had enlisted in army ten years, arriving to change when, facilitated then the birth of M4.
Begin research and development from 1983 up to now, m4 had taken 35 year, the merit is very much, also made world name gun, but defect is likewise outstanding, inadequacy of firepower of bullet of get stuck, fire accidentally, 5.56 millimeter, range is for instance shorter, barrel easy overheat is waited a moment, the U.S. Army retires major general thinks M4 already did not suit an U.S. Army, at least cover troops should change to make type musket newly.
So the issue came, m4 regards American generation name as the gun, already moss-grown really, do not follow to go up age requirement? Answer nature is negative. Because the discussion about M4 is incessant Yu Er, the U.S. Army has made survey a lot of times actually, the answer of result every time is " M4 is reliable still " .
Be in for instance 2006, the United States has had the investigation about M4, and transfer the crowd is retire from what Afghanistan, Iraq goes back to the motherland soldier.
In this findings report, about whether encountering the problem of get stuck, have 19% only retire the soldier chose " be " ; And the problem about function of whether satisfactory M4, of 80% retire the soldier chose " be " .
A weapon can lean after all, still want to relied on actual combat to say to calculate after all, the climate of Afghanistan, Iraq is austere, bigger to the influence of firearms, retire so military answer has referenced sex more. Undeniable, m4 has many drawback really, also caused the U.S. Army's casualties because of these defect, but dependability was achieved 89% (findings report data) , still be very outstanding weapon.
Company of Ke Er spy the vigor to increase M4, these year also improving M4 ceaselessly, new-style M855A1 bullet did aggrandizement on power, penetration. In addition M4A1 is improved with respect to a kind be M4 upgrade edition, gun body comes loose hot property increases, still reformed both hands changes held design (apply to left-hander) .
The U.S. Army has many active service equipment to have very strong vitality, the B-52 bomber that already enlisted in army 63 years for instance, in light of the current condition with M4, should improve only proper, again battle is not a problem 20 years.
