Having a hard time seeing the point of Vanguard Vets and Bikers on Proteus Kill Teams.
Help me understand how they fit into a 9th edition army.
The strongest argument I can make for them is combat squads. You'd take 3 Bikers and 2 VVs to have a high mobility T5 unit with Storm Shields that can move through walls.
Offensively, they don't get Special Issue Ammunition, but they do get power weapons. So the Biker / VV squad becomes your melee option while the regular Vets with SIA become your ranged option.
Aside from that, it's hard to make a case for putting Vets + Bikers + Vanguard Vets in the same unit. Each takes away from the other's strengths.
What am I missing?
