If I have a VCX-100 with a docked Attack Shuttle, Tail Gun on the VCX-100 says I have a primary rear arc weapon now and Locked and Loaded on the Attack Shuttle lets me perform a bonus primary rear arc attack after a primary front arc or turret attack. If I have Veteran Tail Gunner as the gunner on the VCX-100, it says after I perform a primary front arc attack, I can perform a bonus primary rear arc attack.
With this configuration, if I perform a primary front arc attack does that mean I get 2 bonus primary rear arc attacks - 1 for Locked and Loaded and 1 for the Veteran Tail Gunner? It's a lot of points for this config, but for possible attacks it might be worth it - at least in a casual game.
