Panzer

Panzer is monitor, anti-program and anti-personnel program. Developed by the US military, Panzer is a popular program among many larger, well-defended corporate dataforts. With its multifunction mission, a single Panzer program can take the place of several Killer and Ambush programs. A Panzer rumbles along a patrol beat (which may vary, depending on the sneakiness of the sysop), checking IDs at random, just like Monitor (above). However, it has the teeth that Monitor lacks; instead of calling for help, it starts in on intruders itself! (Does 1D6 damage to programs and personnel.) And escaping Panzer is harder than you might think, because Panzer programs contain a routine allowing it to hit targets one subgrid-square away! And as a final insult, Panzer programs come with a codedin re-rezz function, making them hard to kill. The only weakness to the program is that its noisy; it can be "heard" up to 20 squares away. That, and the fact that it can only be operated by systems capable of multi-tasking.
