In April 1944, during a D-Day rehearsal at Slapton Sands, German torpedo boats ambushed and killed upwards of 749 Allied troops. The incident was classified until after the war, with survivors sworn to secrecy. The lack of transparency about the disaster led to missed lessons and unaddressed weaknesses.

On March 16, 1968, during the Vietnam War, U.S. Army soldiers from Charlie Company entered the village of My Lai, expecting to engage Viet Cong forces. Instead, they found unarmed civilians—mostly women, children, and the elderly—and proceeded to kill between 347 and 504 of them. The military initially covered up the atrocity, issuing false reports and suppressing evidence. It wasn’t until investigative journalist Seymour Hersh published the story in 1969 that the massacre became widely known, leading to public outrage and a reevaluation of U.S. military conduct.

In March 1968, the Soviet submarine K-129 sank mysteriously in the Pacific Ocean, leading the USSR to keep the loss secret. The CIA’s Project Azorian, initiated in 1974, successfully recovered parts of the submarine, uncovering valuable intelligence.

For more information, refer to the CIA’s historical release on Project Azorian. (cia.gov)
On August 12, 2000, the Russian nuclear submarine Kursk sank in the Barents Sea during a naval exercise, resulting in the loss of all 118 crew members.

Authorities issued misleading statements for days, and it wasn’t until public outcry that the scale of the loss and the cover-up became clear. For more details, refer to the BBC News reportage on the incident. (bbc.com)
In February 1980, the New Mexico State Penitentiary in Santa Fe experienced a violent uprising, resulting in the deaths of 33 inmates and injuries to over 100 others.

State officials minimized military involvement for years, and the full extent of the tragedy remained little-known for decades.

On June 8, 1967, during the Six-Day War, Israeli forces attacked the USS Liberty, a U.S. Navy technical research ship, in international waters off the Sinai Peninsula. The assault resulted in 34 American crew members killed and 171 wounded. Both the U.S. and Israeli governments initially claimed the attack was a case of mistaken identity. However, many survivors and military officials have alleged that the attack was deliberate, suggesting a cover-up to maintain diplomatic relations. For more details, refer to the National Security Archive’s documentation on the incident. (nsarchive2.gwu.edu)
During the Vietnam War, American bombings targeting North Vietnamese tunnels sometimes struck civilian areas. Misreporting and minimization of errors sustained an image of precision strikes, obscuring collateral damage. The Vinh Moc Tunnels, an extensive network built by villagers to shelter from bombings, stand as a testament to civilian resilience. (vietnam.vnanet.vn)
In 1979, the German company OTRAG conducted a rocket test in Zaire (now the Democratic Republic of the Congo), resulting in an explosion near a village.

In April 2004, former NFL player Pat Tillman was killed by friendly fire in Afghanistan. The U.S. Army initially reported enemy action and fostered a false narrative, only reversing the account under media pressure. The incident exposed military misinformation practices. (history.com)
The cover-ups of these military disasters have had lasting impacts, eroding public trust and hindering effective policy-making. Suppressing information not only concealed operational failures but also led to unnecessary loss of life and international tensions. Embracing transparency is crucial to prevent repeating past mistakes, fostering accountability, and ensuring a more humane approach to military policy. By bringing these hidden incidents to light, we can work towards a military that upholds ethical standards and maintains the confidence of the public it serves. (forcetactician.com)
