Why are US Weapons Supplied to Ukraine Mainly M141 Bunker Defeat Munitions?

The United States has been supplying various weapons and military equipment to Ukraine, with notable emphasis on M141 Bunker Defeat Munitions. These munitions, designed for attacking reinforced positions, might initially seem like a purely offensive weapon. However, the reality of their usage and the strategic intent behind their supply are more complex than meets the eye.

M141 Bunker Defeat Munitions: A Multi-Purpose Munition

The M141 Bunker Defeat Munitions (BDM) are multi-purpose and have an effective range of 500 meters. This weapon is particularly effective against self-propelled bunkers, such as tanks, which are common military targets. While the weapon can certainly be used offensively, its primary function is not to serve as a 'purely offensive weapon.' To provide a more relatable example, a pencil is a versatile tool; one could use it to kill an enemy, but it is much more commonly used for creative and constructive purposes.

Strategic and Operational Context

From a strategic and operational standpoint, the classification of weapons as 'offensive' or 'defensive' can be somewhat arbitrary. An offensive weapon, in this context, might be a medium-range ballistic missile or a cruise missile capable of striking targets in the Russian Federation from Ukraine. Ukraine does have its own short-range anti-ship missiles and plans to improve these. However, the primary focus of US aid has been on defensive capabilities, particularly counterbattery radars.

These radars, programmed to only locate artillery targets within Ukraine's borders, serve a purely defensive purpose. They help Ukraine defend its forces by pinpointing the source of incoming Russian artillery fire and responding with counter-fire missions. The scope of these counterbattery radars was altered to ensure they did not pose a threat outside Ukraine.

Domestic and Tactical Perspectives

The tactical level of warfare often does not distinguish between offensive and defensive weapons. Every lethal weapon can potentially be used in a defensive or offensive capacity depending on the situation. Thus, the classification of M141 Bunker Defeat Munitions as defensive aid in this context does not diminish their offensive potential.

The Flawed Concept of Defensive Lethal Aid

The concept of providing non-lethal and defensive lethal aid to Ukraine is inherently flawed, given the overwhelming and offensive nature of Russia's war effort. Russia is deploying soldiers, mercenaries, tanks, artillery, and other offensive weapons in Ukraine. Fuel-air explosives and cluster munitions are also being used in a manner that is heavily violative of international law and norms. This type of action is clearly designed to undermine Ukraine's defenses and force a capitulation.

From a strategic perspective, the Western democracies should ensure that Ukraine has the right to defend itself with any weapons that could be used to defend their own territory. This includes powerful and offensive weapons when necessary. The current aid strategy, while essential, is hampered by the perception and bloc dynamics within NATO and the broader international community.

Conclusion: The Reality of US Aid to Ukraine

The M141 Bunker Defeat Munitions, while primarily categorized as defensive aid, are still highly potent weapons that can be used decisively in the defense of Ukraine. The reality is that supply decisions are often influenced by political considerations within and between NATO allies, rather than purely strategic or military needs. The international community must recognize that providing Ukraine with any weapon, including offensive ones, is not merely a matter of offense versus defense, but a matter of supporting a nation's right to self-defense.

It delivers a high-explosive dual-purpose warhead (HEDP) effective against masonry or concrete bunkers and light armored vehicles. Its fusing mechanism lets it penetrate soft barriers like sandbags before detonation, making it capable of defeating 20 centimeters (8 inches) of concrete, 30 centimeters (12 inches) of brick, or up to 210 centimeters (7 feet) of wood-reinforced sandbags.
