Starfleet transporters from the "TNG" era onward include a device that can detect and disable an active weapon ("TNG": ""), and a bio-filter to remove contagious microbes or viruses from an individual in transport ("TNG": "", "TOS": "The Naked Time"). The transporter can also serve a tactical purpose, such as beaming a photon grenade or photon torpedo to detonate at remote locations ("TNG": "", "": ""), or to outright destroy objects ("TNG": "Captain's Holiday"). The "TOS" episode "A Taste of Armageddon" mentions Vendikar materializing fusion bombs over targets of enemy planet Eminiar VII in the course of theoretical computer warfare.
