I think these posts might help. They show that titles are very flexible.
Of the two choice you gave, I prefer the first.
If it were me,
The Special Services Division Fleet Maintenance Section
or
The Special Services Division: Fleet Maintenance Section
Your rationale is incorrect. The year's play will be an important play. The building's sprinkler system failed and that is why the damage was so severe.
Hope this help.
