Bots of DOD:Source
 

for Counter-Stike:Source the menu is

bot_add : Adds a bot to whichever team has fewer players
bot_add_ct : Adds a Counter-Terrorist bot
bot_add_t : Adds a Terrorist bot

==============================
I was thinking for Day of Defeat:Source
the menu should be:

bot_add : Adds a bot to whichever team has fewer players
bot_add_a : Adds a Allies bot
bot_add_x : Adds a Axis bot
bot_lvl : Menu to set skill on bots
bot_save : Saves last setting changes
bot_reset : Deletes all setting changes
