tf_bot_combat_improvements.sp provided on post #9 does not work because line 32 in code requires the bot to be cloaked and disguised before it will work.
bot_combat_improvements.sp provided on post #6 works but doesn't seem to change behavior much other than bots occasionally giving random voice commands.
I may not have noticed much of a behavior difference because the Bots on my server already have random difficulty levels.
Maybe it would work better if/when these two plugins were merged.
