I think the C1 Army App has just ported its design from N3 without adjusting for C1 changes... Breaker Combi uses AP ammo but targets BTS. The PDF rulebook has a separate column to highlight the defence stat it targets, but the app does not. Can this please be rectified?
The C1 army tool has several small issues with weapon lists. The Suppressive Fire trait shouldn't be present, either.
