Direct Support/General Support Maintenance Team (MST)

TM 5-4120-394-BD

(3) Estimate repair times for each repair task.

(4) Total the repair task times and determine if the repairs can be performed in the time available.

(5) Determine repair location and, if other than on-site, arrange for recovery of the equipment to the repair site.

d. MT Repairs. If all critical repairs can be made within the available time with the skills, materials, tools, and

equipment at hand, the MT assisted by the crew, will proceed with the on-site repair.

e. MT Assistance. If the damage exceeds the repair capability of the MT, and time is available for an MST on-site

fix, the MST shall be called.

f. ECU Recovery. If time for an MST on-site repair is not available, but the ECU is repairable, the MT shall provide

for recovery of the ECU to a designated collection point.

g. Non-repairable ECU. If the ECU is not repairable, the MT shall provide for one of the following:

(1) Recovery to a maintenance collection point for evacuation to the rear.

(2) On-site stripping (if approved by commander, coordinated with support maintenance).

(3) Abandonment/destruction (if directed by commander).

h. Contaminated ECU. If the ECU is contaminated, the MT shall mark the ECU with contamination markers and

arrange for recovery to a decontamination site.

1-12. Direct Support/General Support Maintenance Team (MST). The MST shall assist the MT as needed, using

direct support maintenance tools and equipment. MST assessment and repair procedures are the same as those of the

MT except at a higher maintenance level. If possible, the MT will tell the MST what tools and spare parts are needed to

perform the repairs. While waiting for the MST to arrive, the crew, under the supervision of the MT, will open up the ECU

and make it ready for the MST to perform the BDAR when it arrives.

a. Repair Priority. Damaged ECU removed to designated repair sites shall be selected for repair by the MST in order

of:

(1) Most essential to the completion of the mission.

(2) Can be repaired in the least amount of time.

1-13. Time Limits for Repairing Damage. In combat the time available for BDAR is limited. One of the factors to be

considered in the selection of a repair site is the amount of time available at the site based on the tactical situation.

a. Estimate of Time to Effect Repair. Every assessment must include an estimate of total elapsed time for all tasks

required to restore the Environmental Control Unit. The time available at the selected repair site must equal or exceed the

estimated time required to accomplish all tasks associated with the BDAR.

b. Time Guidelines. Determining where BDAR will take place should be based on the guidelines in Table 1-1. These

are general rules which must be adjusted by the commander based on his best estimate of how the most responsive

maintenance support can be provided. He must consider the tactical situation, maintenance backlog, personnel, tools,

TMDE, and repair parts available. The guidelines are based on a defensive scenario and can be extended when applied

to the offense.
