CD were you a swiftboater?
No, I was Coast Guard. We served alongside them and shared joint operations and missions and were moored together. Their boats had a shallow draft and were more maneuverable than ours. The other difference was that we lived on the boats for the entire time there; I spent two weeks short of a full year in country whereas Kerry was there less than four months and was transfered out after he received his three purple hearts (as you recall there is some dispute about the seriousness of his wounds and whether they may have been his own fault.)
Check out this thread for info on how the two services interacted:
