[SDK] Source files for some animations missing

I'm retargeting animations for a modded character and noticed that the SDK is missing a couple of the source FBX files.

These files seem to be missing under both "OriginalContent\Models\Characters\Animations" and "OriginalContent\Models\Characters\Animations\Female":

drill_first_aim_down.fbx
rifle_first_aim_down_ironsight.fbx
rifle_first_hip.fbx
rifle_first_hip.fbx
drill_first_aim_down.fbx
drill_first_aim_straight.fbx
drill_first_aim_up.fbx
drill_first_aim_down.fbx
drill_first_aim_straight.fbx
drill_first_aim_up.fbx
