As far as Squad Boxes go, this one is a no-brainer.
General Obi-Wan Kenobi is the most game-changing Unit in all of Star Wars: Shatterpoint, aside from perhaps Luminara. On top of his sustain abilities and excellent mobility (did somebody say "Hello There"?), Obi changes how Hunker tokens work. When he's in the game, they no longer disappear on Engagement, and Galactic Republic units add defense dice to Melee attacks as well. Furthermore, targeted allied Units with Hunker tokens can expend them after an attack to Heal and Dash. If that sounds like a lot, just know it's AMAZING value for 8SP.
For the rest of the box, Cody and the 212th Clone Troopers bring even more Hunker synergy, alongside typical Clone Coordinated Fire traits you've come to expect at this point. While they're mechanically quite solid, I prefer the 212th Clone Troopers for their amazing sculpts more than anything. Much like with the 501st Legion CTs from the Core Box, they are sized perfectly for some personalization. I encourage repping Ghost Company with some Waxer and Boil helmet decals.
I will consistently recommend this Squad Box as a second step into Star Wars: Shatterpoint. Painting and playing with these units is a real treat, and you are going to want more Clone Trooper options for a Galactic Republic list.
