CTCP, CABSA, MBSA

Reference: FMI 4-90.1, Page 3-50, line 2205
Issue: “The CTCP is located within the FSC forward location, one to four kilometers behind the battalion (combat trains).”
Question: If the Combat Trains Command Post is not within the Combat Trains, as the above statement implies, what else is at this location?
(What were we thinking?) See next question.

Reference: FMI 4-90.1, Page 3-50, line 2191
Issue: The FSCs locate … four to twelve km behind their combined arms battalion in the combined arms battalion support area (CABSA).
Question: Is the CABSA [Combined Arms Battalion Support Area] the same thing as the MBSA [Maneuver Battalion Support Area]?
No. Discard MBSA. This was an old idea that somehow escaped the editing process. The doctrine is intended to imply that the FSC HQ and elements not required forward would be co-located in the BSA. However, it does not preclude a CAB from establishing a CABSA with its FSC.

Reference: FMI 4-90.1, Page 3-52, Figure 3-5, Line 2241
Issue: Reference the answer for the above question.
Question: Does an FSC, other than the Combined Arms Forward Support Company, reside in a separate support area or collocate with the BSB?
METT-TC (See above)
