explosives - Does the explosion of TNT include oxidation?

This comment below the question Rocket explosion compared to kT of TNT; has one ever knocked something over at a distance? suggests that

...TNT includes it's own oxidizer...

Explosion isn't the same as combustion and you don't need to add a separate oxidizer to an explosive for it to do its thing.

But technically speaking does the explosion of TNT include any steps that could be considered as oxidative? Can some intermediate products be considered to be acting as oxidizers?

Answer

3 nitrogroups of TNT are rich of oxygen, but the aromatic ring has only carbon and hydrogen atoms.

Therefore oxygen of nitrogroups oxidizes carbon and hydrogen atoms.

There is no principle difference between oxidation and reduction agens being separate molecules, or being different parts of the same molecule.

Note that TNT, in contrary to e.g nitroglycerine, is oxygen deficient, so the amount of available oxygen is not enough for complete oxidation to water and carbon dioxide.

TNT:

$$\ce{2 C7H5N3O6 -> 3 N2 + 5 H2O + 7 CO + 7 C}$$ or $$\ce{2 C7H5N3O6 -> 3 N2 + 5 H2 + 12 CO + 2 C}$$

Nitroglycerine

$$\ce{4 C3H5N3O9 -> 6 N2 + 10 H2O + 12 CO2 + O2 }$$
