I'm counting 17 weapon tokens, 2 grenades.

Then there are 2 tokens that look like power ups, and 2 that look like praetor elites.

I can't find anything anywhere about the power ups or praetor elites, so I'm guessing these were meant to be grenades and were otherwise cut out of the base game.

Otherwise it adds up to 23 correctly.

Everything else has been correct.

AHA! There they are.

So they ARE grenades.

Different TYPES of grenades.

Neat.
