Tired mountain syndrome is a condition in which underground nuclear testing fractures and weakens rock, increasing permeability and the risk of release of radionuclides and radioactive contamination of the environment. Locations said to have undergone the syndrome include the French Polynesian island of Moruroa, Rainier Mesa in the United States, the Dnepr 1 nuclear test site on the Kola Peninsula in Russia, possibly Mount Lazarev in the Novaya Zemlya Test Site in Russia, and Mount Mantap in North Korea.

The ADE 651 is a fake bomb detector produced by the British company Advanced Tactical Security & Communications Ltd (ATSC). Its manufacturer claimed it could detect bombs, guns, ammunition, and more from kilometers away. However, it was a scam, and the device was little more than a dowsing rod. The device was sold for up to US$60,000 each, despite costing almost nothing to produce. It was widely used in the Middle East, and may have led to numerous deadly bombings in Iraq due to its inability to detect explosives. Its inventor, James McCormick, was sentenced to 10 years in prison in 2013 for fraud.

A thermobaric weapon, aerosol bomb, or vacuum bomb is a type of explosive that uses oxygen from the surrounding air to generate a high-temperature explosion. In practice, the blast wave typically produced by such a weapon is of a significantly longer duration than that of a conventional condensed explosive. The fuel–air explosive is one of the best-known types of thermobaric weapon.
Most conventional explosives consist of a fuel–oxidizer premix (black powder, for example, contains 25% fuel and 75% oxidizer), but thermobaric weapons are almost 100% fuel and so are significantly more energetic than conventional condensed explosives of equal weight. Their reliance on atmospheric oxygen makes them unsuitable for use under water, at high altitude, and in adverse weather. They are, however, considerably more destructive when used against field fortifications such as foxholes, tunnels, bunkers, and caves, partly because of the sustained blast wave and partly by the consumption of the oxygen inside it.
Many types of thermobaric weapons can be fitted to hand-held launchers.
