Why is bacillus anthracis a biological weapon?

Answer 1

it mutates cells

Answer 2

Bacillus anthracis is considered a biological weapon due to its ability to form highly resistant spores that can be dispersed in the environment easily. When inhaled, ingested, or coming into contact with open wounds, these spores can cause severe, often fatal, anthrax infection. Additionally, the bacteria can be engineered to be more virulent and resistant to treatments, increasing its potential for use as a weapon.
