Editing Warhammer 40,000/9th Edition Tactics/Grey Knights (section)

=====Pros=====
* The Grey Knights are an army of Psyker Space Marines, each one equal to a Veteran among their Astartes cousins. The standard Strike Squad statline has 2W and 3A (the latter including a baked-in Shock Assault).
* The Grey Knights have strong assault and mid-range shooting. At a minimum, you're getting a storm-bolter and a force sword on every infantry model.
* Great looking infantry models with lots of customization options. They are not really hard to paint either to look decent and [[Duncan_Rhodes|Duncan]] has pretty neat tutorials on them.
* A low model count allows for easy movement and understanding of the game.
* Daemons and Psykers are a massive liability when playing against you. This benefit can't be understated, as GW is now focusing more on the Chaos vs Imperium conflict, and most Chaos armies rely on some form of daemon unit or psyker buff to function properly. 
* Force weapons ''absolutely everywhere'', and they're no longer subject to Deny the Witch, which means you're always putting out 2 wounds to everything in melee!
* All of your Squads can now cast full Smite, not just the Baby Smite of 8E. 
* You are one of the factions that benefit most from the psychic phase. You get an army-wide boost to deny, and every PSYKER unit (except a few honoured knights) know at least 3 powers: Smite, a set power for each unit type, and a new unique power from your BROTHERHOOD sub-faction choice. Your 2 psychic disciplines are good, with some powers that allow you to buff yourself in both offense and defense, hurt others really really badly and TELEPORT ALL ACROSS THE BOARD. EVERYONE CAN CAST. EVERYONE CAN DENY. 
* Pretty much ANY one of your units can start the game in deep strike reserve. Everyone has some sort of teleportation device - and even if they don't, there's a stratagem that allows you to teleport units in anyway. 
* Named character options are abundant, and overall pretty good even if overpriced.
* One of the only armies with Terminator troops. Even Dark Angels lost their Deathwing as Troops. So GK is a good army if you want to bring a pure Terminator army.
* Absolutely no Mary Sue Marines in the codex. For those vets who never wanted the Primaris to exist, in this army they still don't.
* Warlord traits are vastly improved, including one for extra ObSec to even the odds against your dudes.
* 9th Edition's looking to be kind to them, between the general upgrades to all marines as well as all the special stuff available to them.
