Counter-Shooting?!

Hey Guys, just joined the Confrontation family and I am busy preparing my first games with some friends (I'm doing the work, heh). 

One thing I cannot, for the life of me, find something in the german or english rules (nor online) about is the term or the action of 'Countershooting', or a 'Countershot'! On some rare instances I stumble about the term, printed on some cards...

Can someone help me out or point me to the right rules section??

Thank you!


(I hope there will be a Confrontation Renaissance, the universe is just too cool to let it rest..I am sceptical about the Sans-Detour KS though, even though I participated)



Edit: It is actually Counter-Firing...my bad! Still no clue what it means...
