They are just pulling your leg. They know you're cannon fodder
NO actually the bot chat is mostly just to make it feel more real, more human. While statements as to functions may relate to actions performed or abilities, there is no command and control of your individual bot teammates through chat or vsay etc. On the otherhand unlike some other mods you don't have to ask for med packs, revives...
Now if you want bot puppy dogs Mal did implement that in ETQW (patched), but not in FritzBot ET 0.7. I don't know if he ever intended to add much team commands to FritzBot, but it would have meant 2 major changes (bot selection of goals would need to be more complex, and navigation into areas not yet open to a team i.e. cvops holding teamdoors open). And that would have required a lot of work especially since telling an engineer to follow you at the wrong place and time might lose you the match if they had to obey.
