Metro 2033 Redux How to kill ALL of the Librarians in the "Depository" level

I'm playing on the Spartan game mode with Normal DIfficulty.
You need to have all your grenades and A LOT of Military Grade ammo too.
Also, in order to get the Hellbreath you MUST purchase it at Armory station, THERE IS NO OTHER WAY TO GET IT before you reach the "Depository" Level with all the librarians.

Also i knew in advance where all of teh librarians where gonna spawn so i preemptively threw a grenade
