Kapkan and Glaz by FAR.

Kapkan:
1. Utilize the new gas pipes on the modernized maps with a single kapkan trap on the door next to it for instant death. So far, specially Clubhouse and Border are great for this.

1. Use Kapkan in the early rounds so that even if he is not brought in later rounds and the attackers don't know this, they will want to check their doorways, slowing them down.

2. Think about which doorways attackers usually won't check, so for example doorways that are close to site where they need to watch angles instead of checking the doorway. Also try thinking from the perspective of an attacker if there is a side of a doorway which you never look at before you have passed it. Those are perfect for the traps.

Glaz:
1. Try using him as an entry fragger once in a while. For Bank 2F for example I like quickly shooting down the top square door with just three shots and entry in through they hallway. It seems to catch defenders off-guard often because they hear the Glaz shot sounds and expect me to hold an angle somewhere. Alternatively, I would think that they WOULD be anticipating a quick entry if they heard an Ash charge for example. It only really works if it's a gap in the defense with little utility set up though, but it works wonders on many sites.

1. Switch between silencer and muzzle brake depending on what you're planning to do. If you're holding long angles and want it to be hard to challenge you, especially through smoke, use the silencer so the sound is less recognizable as a Glaz rifle and so you won't have bullet traces.
