I don't think #'s 12 & 13 are on the right track, I like the feel of #11 just not sure as it doesn't represent or say what we do or signify Canada? It does look good though!
#18 looks cool, different than I was thinking but I like it.
Would it make sense to add our full name below so people know what we do? Or should we add tag line?
Have been going back and forth on "STRAC" or " S.T.R.A.C.", your thoughts? Marketing to Fire Departments, Emergency Response Teams, Military and even possibly some SWAT?
