Protect yourself against Nova gas.

Now many of you may have stopped right there, but how many of you have actually bothered to try out its PRO effects?
PRO: +Reduce the effects of Flash and Concussion Grenades, and reveal the position of a flashed or stunned enemy.

I use this as my main 3rd perk and here's what I've acknowledged from it,
The reduction of flashbangs and concussion grenades are tremendous:
-Only stunned for half a second by concussion grenades
-Flashbangs will only last half a second and will still give you full visual of the screen

Combined with Flak Jacket, you literally become a walking tank, to the brink where explosives or any special grenades are of any issues to you. This perk will come in handy for when playing objective-based game modes such as headquarters, but is also great for general use.

Now regarding Tactical Mask Pro's second effect (revealing enemy position), it definitely comes in handy for flushing out an enemy in a tight room for when you don't know their position.

*There is also a case where if you stun or flash an enemy equipment (i.e. claymore, motion sensor, etc.) a hitmarker will indicate that you managed to distort the equipment. This will cause confusion for the player in determining whether what they stunned/flashed was either an enemy or an equipment (usually for when clearing out rooms or corners). WIth TM Pro, the ability to locate an enemy will resolve this issue.

Now I also know that it's quite a pain in the ass to try to to complete the Pro challenges, which requires 20 kills each from a flashed, stunned, and gassed enemy, but mind you that it will all be worth it. But I'm a nice guy, I don't want you to feel any stress while trying to unlock the pro version. So here is a cheap way but simple way of attaining it:
You must login or register to view this content.
(Yes, I'm talking to you lazyass)
*Also, it doesn't have to be your own special grenades. An enemy can be stunned, flashed, or gassed by his own special grenade or another persons, and the kill will still count towards the Pro challenges.
Here's a video of the effects of a flashbang when using TM Pro, as well as some analysis:

Updated: Missing some info + a little extra more.
I will try to upload a video of the stun effects sometime today (depending on how quick theater mode responds to the upload).
