There's a time for complex strategies, and there's a time for brute force. Show these terrorists what war is.
you will see here one of those sets that are extremely stupid but work extremely well, and so much so that you will be able to do all (probably) maps in ready or not on rank S

Flash grenades are one of the most powerful weapons in ready or not but you usually only take 2 or 3 of them.
The question is why limit yourself when flashes are so powerful?
that's the point, you don't have to do it
in this build you and your team will have 110 flashs for use!
If you use the same build,everyone on your team will have 22 flashes at your disposal.

18 in your main grenade launcher and an additional 4 in your secondary.

You also have a stun gun with a total of 6 shots for emergency situations.

Your pistol doesn't matter, and it's empty anyway.

There are 5 people in your team, each has 22 grenades, which makes 110 in total
Now you know why this guide is called that hehehe

Playing with bots in commander mode adds another advantage to this build.
With a bit of luck, you'll get a member with the Riot Control skill on your team.
Which gives you extra stun time so you have more time to take control of the attacked room

This set has one big drawback:friendly fire
If you're not careful or your bots/players are targeted, your score will be reduced by 30 points. Of course, if you don't care about the mission results, this isn't a problem, but if you want to get those S at the end of the mission, you need to be careful.
Another problem is wearing a light vest instead of a heavy one. Most people use them anyway, but I find using a light vest in this game, where you can get shot down like a bird by a hobo with a shotgun on the other side of the map, quite... problematic.

For me, this build is extremely overpowered and can be used on any map. It has its pros and cons, but hey, nothing is free right?
If you have any ideas on how to improve this or have any questions, please leave a comment.
if not, try it in the game and make those bastards go blind
