Introduction
In the realm of military weaponry, light machine guns (LMGs) play a crucial role in providing infantry units with the necessary firepower to suppress enemy positions and support maneuvering troops. Among the most iconic LMGs in the U.S. Army's arsenal is the M249 Squad Automatic Weapon (SAW). This weapon has been a staple since its introduction in the 1980s, but as technology and warfare evolve, so too does the need for more advanced weaponry. The purpose of this blog post is to provide a comprehensive understanding of what LMG the Army uses, focusing primarily on the M249 and its upcoming successor, the XM250.
As you read, you'll learn about the historical context of these weapons, their operational characteristics, and the implications of transitioning to newer technologies. Whether you're a military enthusiast, a tactical gear aficionado, or simply curious about the evolution of military firearms, this post will offer valuable insights into the world of light machine guns used by the U.S. Army.
Historical Context
The M249 was adopted to meet the U.S. Army's need for a capable LMG that could provide sustained fire. Its roots trace back to the U.S. military's evaluation of various machine guns in the 1960s, as older models like the M60 and the Browning Automatic Rifle (BAR) were deemed inadequate for modern warfare. The M249 was introduced in 1984, based on the Belgian FN Minimi design, and quickly became a critical component of infantry tactics.
However, as combat conditions have evolved, so have the requirements for military firearms. The U.S. Army recognized the limitations of the M249 in various environments, leading to ongoing assessments for a replacement. This culminated in the selection of the SIG Sauer XM250 as part of the Next Generation Squad Weapon Program.

Design and Features
The M249 is a gas-operated, air-cooled light machine gun that fires the 5.56×45mm NATO cartridge. It features several design elements that enhance its usability in combat:
- Belt-Fed System: The M249 is primarily belt-fed, allowing for a sustained rate of fire, which is essential for providing cover during maneuvers.
- Quick-Change Barrel: This feature enables soldiers to rapidly replace an overheated barrel, crucial for maintaining fire during extended engagements.
- Folding Bipod: The adjustable bipod facilitates stability in various firing positions, whether prone or supported.
- Weight: Weighing around 17 pounds (including a 200-round belt), the M249 provides a balance between portability and firepower.
Operational History
The M249 has seen action in numerous conflicts since its introduction, including the Gulf War, Afghanistan, and Iraq. Its reliability and effectiveness have made it a trusted choice among troops, though it has faced criticism for its performance in sandy environments and its weight. Soldiers have reported issues with maintenance and the weapon's ability to handle dust and debris, leading to malfunctions.
Feedback from Soldiers
The M249 has garnered mixed reviews from military personnel. While many praise its accuracy and firepower, others express concerns about its weight and maintainability. Surveys conducted among soldiers have indicated that while a majority are satisfied with the weapon's performance, issues such as jamming and difficulty in cleaning have been highlighted.
Transition to the XM250
Background on the Next Generation Squad Weapon Program
Recognizing the need for a more advanced LMG, the U.S. Army initiated the Next Generation Squad Weapon (NGSW) program. This program aims to replace both the M4 carbine and M249 light machine gun with more efficient and effective alternatives. The XM250 was developed to meet these goals, incorporating modern design elements and materials.
Design Characteristics of the XM250
The XM250 features several innovations compared to its predecessor:
- Weight Reduction: Weighing approximately 13 to 14.5 pounds with a suppressor, the XM250 is designed to be lighter than the M249, enhancing maneuverability for the operator.
- New Ammunition Type: The XM250 is chambered for the 6.8×51mm cartridge, which offers improved performance against modern body armor compared to the 5.56mm NATO round.
- Advanced Optics: Integrated with the XM157 fire-control system, the XM250 provides soldiers with enhanced targeting capabilities, including a laser rangefinder and ballistic solver.
- Enhanced Durability: The design focuses on reducing the potential for malfunctions, with a strong emphasis on materials that withstand harsh combat conditions.
Testing and Fielding
As of early 2024, the XM250 has begun to be fielded to select units, including the 101st Airborne Division. User testing is crucial to gather feedback on its performance in real-world scenarios, enabling further refinements before full-scale production and deployment.
Comparisons Between M249 and XM250
Performance Metrics
When comparing the M249 and XM250, several key performance metrics stand out:
- Rate of Fire: The M249 has a cyclic rate of fire of approximately 850 rounds per minute, while the XM250 is designed to maintain similar rates but with improved reliability.
- Ammunition Capacity: The M249 typically uses 200-round belts, whereas the XM250 has a standard combat load of 400 rounds in four 100-round pouches, providing greater operational flexibility.
- Ease of Use: The XM250's design incorporates newer technology that aims to simplify maintenance and improve overall user experience compared to the M249.
Tactical Implications
The transition from the M249 to the XM250 has significant implications for infantry tactics. With a lighter, more effective weapon system, soldiers can engage targets more effectively while maintaining mobility on the battlefield. This shift aligns with modern warfare strategies that prioritize rapid movement and adaptability.
The Role of Tactical Gear in Supporting LMG Use
Importance of EDC Gear
As soldiers rely on LMGs like the M249 and XM250, the importance of everyday carry (EDC) gear cannot be overstated. Proper tactical gear enhances the operational effectiveness of these weapons. Here are a few items that can complement LMG use:
- Tactical Vests: Designed to carry ammunition and equipment efficiently, tactical vests allow soldiers to access their gear quickly while maintaining mobility.
- Firearm Accessories: Items such as optics, grips, and bipods can enhance the usability of LMGs, allowing shooters to engage targets more effectively.
- Maintenance Kits: Regular maintenance is vital for reliability. Portable cleaning kits can ensure that LMGs remain operational even in harsh environments.
