Pros And Cons Of M4

The M1's early performance problems gave it such a bad reputation that after the 1939 National Matches, the National Rifle Association was able to get Congress to look at the problem. A major redesign was ordered on October 26, 1939 and Garand redesigned the rifle to operate with gases tapped from a gas

American soldiers were using fairly new weapons compared to previous conflicts. The fully automatic assault rifle was new addition to the American arsenal. A prime example of the sheer power and deadliness of an automatic rifle is the M1918BAR (Browning Automatic Rifle). This gun was the first of it’s kind for American forces. Though it was a bit heavy, it had stopping power. It blasted the .30-06 Springfield round down range at 2,822 f/s. Although the iron sights weren’t all that great, the aperture view did the job quite well for targets that were a little ways out. Due to the success of this weapon, Browning set out to create a better, stronger version of it for heavier combat. The M1919 Browning Heavy Machinegun was deployed. This monster of a gun was usable without a bipod, but heavy and hard to aim without. With a 600 round per minute rate of fire from a direct feed belt, the Browning was one of the

It influenced future generations of soldiers and equipment to advance both tactically and technically, greatly increasing the multi-role diversity and capabilities of the Air Defense Artillery systems of today’s United States Army. Compared to the Patriot Launcher Missile system, it showed that Air Defense units could be multifaceted. Like the M42 Duster (SPAAG), the Patriot system demonstrated excellent destruction ratio for aircraft but the system also worked well in defense of TBM’s (Tactical Ballistic

Overall, the Ruger Air Magnum Combo air rifle is a good product that delivers a lot of power and many customers are satisfied with their

The M249 fires a 5.56x45 millimeter round that can fire up to 850 rounds per minute from a 100 round linked drum and can accurately engage a target out to 1,000 yards. Just like its 1940s counterpart it is used on the front lines for its light weight and maneuverability. The M249 will soon be replaced with the M27. The medium weight machine gun that is in use today is the M240G which weighs in at 25.6 lbs at 49.7 inch’s. The M240G can fire up to 950 rounds per minute from a 100 round linked drum and can accurately engage and eliminate a target out to 1,800 yards. The M240G, just like the M1919, fires a 7.62x51 millimeter and was placed on the front lines and in aircrafts for its high caliber and its high rate of fire. Lastly the heavy machine gun that we use today is the same that was used in the 1940s, the M2. There have been very few changes, such as parts made out of lighter medals.

Since 1985, eleven different versions of the High Mobility, Multi-Wheeled Vehicle (HMMWV) have been in service. The Joint Light Tactical Vehicle (JLTV) is being developed by the Army and the Marine Corps as a successor to the HMMWV. The Department of Defense (DoD) initiated the JLTV program to replace its aging fleet of the HMMWV. The purpose of this essay is to determine if the high cost of the JLTV should preclude it from replacing the HMMWV as outlined in the 2010 Tactical Wheeled Vehicle Strategy. Because of the cost, an inability to meet joint requirements and the presence of feasible alternatives, the Department of Defense should not continue acquisition of the JLTV.

In September 2011, the Senate Appropriations Defense Subcommittee voted to cancel the Army and Marine Corps' Joint Light Tactical Vehicle (JLTV) in their version of the fiscal year 2012 defense bill (Munoz, 2011). This measure could have completely shut down efforts to replace a thirty year-old fleet of Humvees, loyal but potentially outmoded tactical wheeled vehicles. The Army's Modernized Expanded Capacity Vehicle program has been a project set to replace the High Mobility, Multi-Wheeled Vehicle (HMMWV) family in the works for years. The project, however, continues to be stymied by budgetary constraints. Per-vehicle costs for the JLTV begin at $250,000 and are likely to climb, as Lockheed-Martin secured a preliminary contract for engineering, design, and development. The high cost of the JLTV does preclude it from completely replacing the HMMWV, and yet cost does not preclude the JLTV from supplementing the Army's fleet. A middle-ground solution is the best method of maximizing initial investments, while also banking on the robustness of national security.

“This variation has a design of a smaller breach that fired a cartridge of 76.2x585R, allowing a breach that will automatically open after the firing of each cartridge” (Ordnance, T. O, 1920). This was an innovative concept that allows the firing of multiple rounds at a greater rate to help with the adjustment needed when firing at an aircraft traveling at a high velocity, attitude, and altitude. “The muzzle velocity of this weapon firing a 15-pound shell, with either shrapnel or explosive charge, is 2,400 feet per second” (Ordnance, T.O, 1920). The maximum

The M-16 is infamous for its accuracy on the battlefield especially at longer ranges. Both assault rifles share the same 5.56mm projectiles, which provides significant stopping power.

Soldiers have concerns about the upcoming gunnery. Some of the E-4’s will be tank commanders. Some feel that they may not get the mentorship needed before gunnery.

Comparisons can be drawn between the T-34 and the U.S. M4 Sherman tank. Both vehicles were the base of their countries’ armies and both were given to the countries allies. Both were designed for mobility and were easy to manufacture and maintain, sacrificing some performance for these goals. Both chassis of these tanks were used for the creation of new support vehicles. And neither were to withstand the might of the German Tiger and Panther tanks, but did outnumber them by a large number. The chassis also formed the base for a bridge layer, self-propelled gun platform and armored recovery vehicle. It was even used as a "fast personnel carrier" to the horror of German troops now being swarmed by T-34s with Soviet infantry. Other notable variants

through 2009; however, a number of other manufacturers offer M4-like firearms. The M4A1, along with the M16A4, has mostly replaced the M16A2 ; the U.S.

8 million of these have been made which is a relatively small number when compared with the AK-47s 100 million (Phillip Killicoat, 2006). From 1955 or the Vietnam War the closest thing to competition was the M16. But was dominated by the AK-47 due to the reliability of the AK and the ease of production verses the clinical M16 with jammed repeatedly, causing stoppages and therefore the ability not to fire.

Considering that the military’s logistical structure hasn’t had a major improvement in over 60 years, the idea of streamlining and consolidating systems would be a welcome and much needed change. I currently work in the ammunition field for the U.S. Army and have done so for the past 18 years. The changes that the Marines are beginning to implement will help to free up resources and cut funds that could be used for other projects.
