How bout this...
Thermobaric weapons are considered to be one of the most brutal war weapons that exist. The missiles are filled with a highly explosive fuel and chemical mix, which on exploding can cause supersonic blast waves that can obliterate everything in their path, including buildings and humans.
Much better.
Conventional explosive such as TNT must carry their own oxidizers as nitrates. TNT is trinitro toluene. Basically a benzene with three nitrates attached to the benzene ring. The nitrates on the benzene ring are the oxidizer. Thus the are a point weapon of much destruction but have a limited radius of lethality as compared to a fuel air weapon also called thermobaric weapons. The thermobaric weapon is basically a weapon filled with petroleum distalists. It primary charge creates a mist cloud of these distalits like gasoline. It is then ignited by a secondary that then explodes the cloud. It creates a huge pressure wave that kills in a wide radius. A soldier in the blast radius would have his lungs collapsed and his ribs broken and become knives into his lungs.
The ugly beauty of this weapon is its blast radius and the fact that the oxidizer is just the air. Thus, all the pounds of conventional weapons that need oxidizers is not needed and thus pound for pound is most efficient.
