What is the most common type of explosive used in military ordnance?

TNT, or Trinitrotoluene, is the most commonly used explosive in military ordnance due to its long history of usage, stability, and effectiveness. It has been a standard explosive for military applications since the early 20th century, known for its reliable performance under a variety of conditions. TNT offers a balanced combination of sensitivity, safety in handling, and brisance, making it ideal for use in munitions, bombs, and as a filling for artillery shells.

TNT's chemical stability means it can be stored for long periods without significant degradation, which is a crucial requirement for military supplies. Furthermore, its ability to perform consistently across a range of temperatures and conditions makes it a preferred choice for various applications. This historical reliability has established TNT as a benchmark against which other explosives are measured.

Other explosives like RDX and ANFO are also widely used in specific military and civilian applications but do not match the overarching prevalence of TNT in traditional military ordnance. Semtex, while effective and known for its plasticity and use in demolition and assassination, is not as commonly utilized or stockpiled by conventional military forces compared to TNT. Thus, the widespread and historical usage of TNT in military applications supports its identification as the most common
