I had an idea of adding the little boss robots like Steel Gauntlet, Shortstop Scout, Rapid Fire Huntsman, Samurai Demo, and so on. It would be cool if you would implement the "support" or "semiboss" tag that defines these templates as occasionally turning players into these templates after the tank is destroyed and also add the cvars tank_allow_support_templates for allowing templates to be used on a specific map, and tank_support_template_percent for setting the percentage of a player being randomly selected to become that template on that specific map in stt.cfg file. And also, if you are going to implement the "sappable robots thing", on sapping them, they will likely be stunned and unable to use weapons for 7 seconds. They may also be backstabbed and instantly killed, to even this out.
