WASHINGTON — The Pentagon’s most up-to-date package deal of weapons for Ukraine consists of relics from the Chilly Battle to assist blunt Russian advances and restrict their means to maneuver throughout an anticipated spring offensive.
These weapons, M21 anti-tank land mines, have been in service with the Protection Division since no less than the early Sixties. An unknown variety of them will likely be despatched to Ukraine as a part of a $325 million package deal of help from U.S. army stockpiles that was introduced this week, the thirty sixth such switch of deadly matériel to Kyiv since August 2021.
M21 mines — massive metal-bodied weapons which might be often buried and explode when a car drives over them — comprise a specialised warhead constructed to punch by inches of armor plating.
“Anti-tank land mines are an essential defensive functionality towards Russia’s tanks and armored autos, serving to Ukraine’s forces repel Russia’s assaults and form the battlefield to Ukraine’s benefit,” Maj. Charlie Dietz, a Pentagon spokesman, mentioned in an announcement on Thursday.
The choice to supply M21s seems to fastidiously thread the needle between numerous areas of concern, given the controversy that has accompanied the usage of land mines for many years.
One difficulty is legality. As an anti-tank weapon, the M21 just isn’t banned by the 1997 Ottawa Conference — a global treaty signed by 133 nations that prohibits the stockpiling and use of anti-personnel mines, that are often a lot smaller and kill or maim individuals who step on them.
By comparability, anti-tank mines usually require a pair hundred kilos or extra of strain to detonate, reminiscent of from a truck or tank. In contrast to some fashions of American-made anti-tank mines, the M21 can’t be fitted with any secondary fuzes that might enable booby-trap gadgets to be added, which additionally retains it from doubtlessly operating afoul of sure provisions of the treaty.
Ukraine is a signatory to the Ottawa Conference, whereas the USA and Russia aren’t. The Biden administration has mentioned, nonetheless, that it will use anti-personnel mines solely within the protection of South Korea.
One other difficulty includes post-conflict issues: whether or not the weapons could be simply positioned with steel detectors and ground-penetrating radars, and the way lengthy they continue to be deadly as soon as planted.
Though the U.S. army developed anti-tank land mines through the Chilly Battle constructed principally of plastic to make them laborious to detect, the M21 is steel and could be comparatively a lot simpler to search out when mine clearance efforts start.
The latter concern, nonetheless, stays unaddressed: Like mines of its period, the M21 has no self-destruct function. So Ukrainian troops will most likely be anticipated to fastidiously map the place they place the mines for later clearance operations.
Based on a 2002 report from the Common Accounting Workplace, now generally known as the Authorities Accountability Workplace, the Pentagon had greater than 178,000 M21 mines stockpiled on the time. The report says that the U.S. army final used anti-tank mines throughout Operation Desert Storm in 1991, although not the M21.
The M21 is taken into account a “heavy mine” at about 9 inches in diameter and eight inches excessive, and weighing 17 and a half kilos. When triggered by a downward pressure of almost 300 kilos, the mine explodes, throwing a curved metal plate upward into the focused car’s hull, wheels or tracks.
A U.S. Military technical handbook notes that the M21 can penetrate a three-inch armor plate at a distance of 21 inches.
The M21 is the second sort of anti-tank land mine the USA has offered to Kyiv.
In September, the Pentagon introduced it will ship 1,000 155-millimeter artillery shells it calls RAAMS, for Distant Anti-Armor Mine System, that are fired from howitzers and create momentary minefields amongst enemy forces.
The shells break open midair and launch 9 small puck-like munitions that fall to the bottom unguided, with every containing about one and 1 / 4 pound of excessive explosives.
Every small mine incorporates a magnetic sensor that causes it to blow up when a car approaches. There are two variations: one meant to self-destruct after 4 hours, the opposite after 48 hours.
The latest knowledge obtainable exhibits that the Pentagon had despatched 14,000 of the shells to Ukraine as of April 4.
Ukraine’s military has lengthy used Soviet-era TM-62 anti-tank mines in its conflict with Russia, as have the Russian invaders. Whether or not the availability of M21s alerts that Ukraine’s inventory of TM-62s is operating low, or that the M21 is required for different causes, is unclear.
