We could use more bombs in the game, so I'de like to make a suggestion for one.
A ripper or 'Bleeder.' This is effectively a better pipebomb, with razors and nails glued to the outside.
This bomb would cause a lot of damage to armor, and cause decent bleeding on those hit.
And maybe it works with a 'contaminate' command. where you take a vial of blood that has a disease, and use it to contaminate the bomb and spread the disease among those hit.
