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:

Cool could never be bother getting this to pro so had no idea what it done thanks for the info
it was just the nova kills the got me i almost got it then prestiged think i will give it a shot this time though i hate being flash/stuned lol

Use flak jacket and this combined, I've been using this setup since the first week and its amazing.

Yea, I use a LMG class with Flak Jacket, Hardened and Tac Mask. FTW.

Might use that setup tactical mask, flak jacket with my stakeout. Run in and rape while surviving everything thrown at me

I'd recommend Marathon with the Stakeout. You need to get close to the enemy because the closer you get the more damage you can get.

SO sure Tac Mask pro is good to have, yet it's a pain in the ass to get. Just like FlakJacket Pro.

Yeah it took me a whole day of playing to get it, the Nova Gas was being a bitch for me, but definitely worth the grind

I honestly underestimated Tactical Mask, but after reading this, I'll give it a try

This has been on my list of things left to get.....
Only that and flak with scout......

I do want it so bad , i want to be a tank already damn powerful with flak
