New Content
Added a new “Ready Up” system for competitive matchmaking.  
Added new player level icon for when surpassing level 999.

Added remaining Lesson video tutorials.  
Added “Paper Plane” Tattoo for Security, and “Geometric A”, “Geometric B”, “Sword and Flowers” Tattoos for Insurgents.

Gameplay Improvements
Versus Firefight match length adjustments:
4 rounds total.

Win limit 3 rounds.
Reduced the number of fire support rounds fired for:
Explosive Artillery
Smoke Artillery
Chemical Mortars
Explosive Mortars
Smoke Mortars
Rocket Barrage
Reduced vehicle usage in Push to only spawn one vehicle at the start of the round, and another if the attacking team runs out of waves while still attacking the first objective.

Slightly increased overhand grenade throw range.
