I was unable to watch the video due to the server I´m on. However, it is a common misconception that all thermobaric charges use atmospheric oxygen.
A thermobaric charge does not need to use atmospheric oxygen to be considered thermobaric. All oxygen can be present in the chemical structure of the
explosive mixture and the oxidation of the metal powder still slows the blastwave and increases heat output, resulting in the desired thermobaric
effect. These effects are a slower moving, stronger pressure wave and high heat production, hence thermo (heat), and baric (pressure). This is
especially useful when destroying caves or harder structures where atmospheric oxygen may be inadequet.
There are charges however, such as the thermoberic version of the RPG invented by the Russians, that do require oxygen from the air. I think the ratio
was something like 70% Al powder 30% TNT. The Al surrounded the spherical TNT booster charge. Anyway, thought this information might be interesting.
