Besides for that she should of course come with a whole suite of Coast Guard weapons. According to Wikipedia (http://en.wikipedia.org/wiki/Equipment_of_the_United_States_Coast_Guard),
QUOTE
From 1986 until 2006, Coast Guardsmen on patrol were armed with Beretta M9 9 mm pistols. The Coast Guard has transitioned to the .40 S&W caliber SIG-Sauer P229R DAK, completing the changeover as of April 2006. Other small arms include the M16A2 rifle and M4 Carbine variant, as well as the Remington 870 police magnum riot shotgun, from which the Coast Guard employs both lethal and non-lethal rounds. The Coast Guard recently replaced the M60 machine gun with the FN M240 machine gun, which is typically mounted on vessels, aircraft, or used in shoreside machine-gun emplacements. Many Coast Guard units are also equipped with the .50 caliber M2 machine gun. Weapons above .50 caliber are considered "weapons systems", rather than "small arms". Specific units also have the M-203 grenade launcher.
I've also read that the Coast Guard uses a .50 Beowulf entry carbine, which can be created by using a conversion kit on a typical AR-15 style rifle, for those situations where you want a lot of kinetic energy and tissue trauma but want better ballistics than a shotgun would offer.
Here's some .50 Beowulf links:

So, not only could Barbie have a carbine chambered in .50 Beowulf, but she could also have a little pink conversion kit for her AR-15 style rifle.
Also, think of how much cooler it would be to buy a bunch of scale model coast guard ships instead of a Dream Home or whatever.
I'm really surprised that Mattel hasn't gone and done Coast Guard Barbie yet. It seems to me that of all the branches of the military, Coast Guard Barbie would have the most for her to play with.
