The ladies of the female brigade of 'Real Men' got to experience what is possibly one of the most infamous training exercises in the South Korean military - the chemical warfare training, where a squad is locked inside a concrete room, which is then pumped full of tear gas!

Although the intensity was lessened to compensate for the female soldiers, that didn't stop G.NA and Hyeri from sprinting out the door, tears in their eyes and drool coming out of their mouths. The fact that their masks weren't attached properly didn't help!

Check out the harrowing clips below.
