Hello guys!

In this guide, I'll show you a 100% effective method to make the BOTs properly respond to your radio commands in Competitive Matches on CS:GO.
First of all, this guide will only work effectively if you have strictly ONLY ONE player missing in your team. If you have two or more players missing, this method will work only sometimes (don't ask me why!)

Getting Started
Before the beggining of the round, choose between the 4 players who will give the command to the bot. This is very important. Only one person should give the command. If other person gives another radio, even if it is the same one, this trick may not work.

Second Step - Silence
After choosing the player, at the beggining of the round, is VERY IMPORTANT that all the other 3 guys DO NOT give any radio command, as i said before, and they ALSO MUST NOT speak on the microphone while this is being done.

Third Step - Watch your time
When the freeze time ends, one of the players automatically says a motivational radio message, like "Let's go get them, fellas!". To give the next step, the chosen player should wait till this message ends. You can wait a second more after that, just to be sure.

Final Step - The command
After all of this, the chosen player is free to give the radio command! You will see that, following these steps correctly, the BOT will say "Affirmative" or "Roger That" when you finish giving the command. I highly recommend giving the "Hold position" (Z > 4) command to the BOT, so this way, he will stay put next to the spawn area, protected from the other team till the first player eventually die.

Additional information
There are a couple things that may make the BOT leave his position even if this trick works, so watch out to make sure these things don't happen:
1- If you are in the Terrorists team, DO NOT drop the C4 on the ground, because the BOT will always go straight ahead to get it.
2- If you are in the Counter Terrorists team, try to avoid the C4 to be planted, because the BOT will always leave his position to go and try to defuse the bomb once it is planted.

That's it guys! I hope it helps!
