Pete complains:
"Isn't that why the USCG was created,and put under the Treasury Dept instead of the War Department?"
USCG might be outgunned by the smugglers... ;)
@Fishrrman Doesn't seem likely. The cutters have naval "rifles" on board. Yeah,they are smaller than the gunnery on Naval line ships,but should be sufficient for USCG needs.
The smaller boats they use to board ships with have 30cal belt-feds on them,and some of the boarding crews carry whatever they call the newest version of the CAR-15.
Not to mention there is few areas they will go where there won't be USN or USAF fighter-bombers on call from not that far away.
You would really have to be a fool to engage the USCG in a gun battle. Chances are none of them have ever been in one,and would get excited and shoot you with every bullet,rocket,and missile they have.
