Star Trek TNG Alt Starfleet help needed

[garrowolf]

I am working on an alternate version of starfleet for a fan fiction for Star Trk the Next Generation. I've divided Starfleet up into four major sections:
Troubleshooter - Diplomatic, anomalies, etc. This is what the Enterprise does.
System Defense - Actual military ships to deal with invasions and piracy
Exploration - They travel to new places. Science vessels here.
Emergency - Hospital ships, disaster relief, etc.

I just need better names for these sections. Any ideas?

Generally speaking, exploration was Enterprise's primary mandate ("seek out new life and new civilisations"), though they also tended to get heavily involved in the Troubleshooter role. Science vessels would tend to be used more to follow up on the initial discoveries of the exploration vessels.

Namewise I'd suggest:

Expedition
Constabulary
Evaluation
Alleviation

Well I was trying to find some terms that sounded more military.
I wanted to have more specific roles for specific groups instead of having them do a little of everything. I know that it is better for a TV show but it doesn't make as much sense to me.
