MAINTENANCE TEAMS (MT)
a.
The MT and Assessor operate out of the company or battalion trains.
The MT Assessor performs his
assessment and the maintenance team completes repairs if possible at the damage site.
If the site is within direct fire or
under enemy observation, movement to a more secure site in concealment may be necessary.
This is still considered on-
site.
b.
If the howitzer has been left unattended in the forward battle area, the immediate area of the howitzer should
be checked for mines, and the howitzer should be checked for booby traps before starting the battle damage assessment.
The MT should also make the safety checks listed in paragraph 1-14e.
c.
The MT assessment will be more thorough than the crew’s, using unit maintenance support tools and
equipment as needed MT assessment includes.
(1)
Reviewing the crew’s out-of-action report, if available.
(2)
Interviewing commander and crew, if available.
(3)
Visually inspecting damaged parts and systems.
(4)
Performing a self-test.
(5)
Making tests with unit test equipment, if required.
(6)
Performing additional vehicle operational tests, as necessary.
d.
Using this information and following the steps in paragraph 1-15c, the MT will:
(1)
Determine what must be repaired or replaced.
(2)
Determine sequence and priority of repair actions.
(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 howitzer.
e.
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.
f.
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.
g.
If time for an MST on-site fix is not available, but the howitzer is repairable, the MT shall provide for recovery
of the howitzer to a designated collection point.
