Got a friend who is a Special Warfare Combat Crewman (SWCC), the Navy's modern version of the Brown Water Navy. He is getting me a lead on the use of the LCM-3 in early Vietnam river ops by the US but only 3 were ever tried before they were replaced. Initial experimental designation was LCM-P (Landing Craft Mechanized-Patrol)
Seems it had the .50's mounted but with the modern "U" shaped gun shield, a canopy over the wheel house, and an M60 mounted port and starboard amidships. He found a limited description by accident but we are having trouble finding pictures. I have an Italeri kit on the shelf and may build it based on what I have of the description. I am all about accuracy but since alot of the units bastardized their boats anyway it leaves some room for artistic license and kit bashing fun.
Another easy Brown Water Navy project is my latest creation. It is a 1/72 PTF "Nasty" class patrol boat. I kit bashed the Revell PT-109 and the old Airfix MTB kit. There are tons of plans and photos on the net. I am considering converting the bare bones Lindberg 1/32 PT-109 hull to a 1/35 PTF Nasty. Have a fine Navy day!
