I am considering entering this campaign after finishing up with Not a Tank Destroyer and Unfinished Business. Finding a subject that interests me, lies within my capabilities, will not take too much time, and will not cost much has proven extremely tough. At this point, I have identified a few options.
Option 1: A jeep with 4.5 inch naval rocket launchers as seen in Plan 9 from Outer Space. This vehicle actually existed but was ultimately abandoned because Jeeps were simply too small to serve as a stable firing platform for the naval bombardment rockets. As best I can tell, Ed Wood simply spliced United States Navy weapon test footage of the test vehicle into his film. This subject would require a jeep, which I already have, scratch built launchers, and scratch built 4.5 inch naval rockets. I have enough pictures of the vehicle to make a decent stab at this.
Option 2: USS Houston, used for a scene near the end of The Hunt for Red October where USS Dallas intentionally becomes the target of a Soviet torpedo, then drops counter measures and breaches to evade it. A number of real Los Angeles class submarines appear in the movie as USS Dallas, but USS Houston is featured in the culminating battle scene. United States attack submarines do not display names, docking markings, or hull numbers accept during work up, which is why all the real submarines playing USS Dallas look almost exactly the same. However, the filming miniature used for underwater scenes of USS Dallas differs from a real Los Angeles class submarine, having a fictitious cruciform tail arrangement. While I do not own a model of USS Houston, they are cheap and readily available. I have a fair number of subs in my collection and would enjoy adding USS Houston which is a real vessel, not a fake movie prop that does not really interest me.
Option 3: A Japanese Ground Self Defense Force T-90 Main Battle Tank as featured in Sengoku Jieitai 1549–Samurai Commando: Mission 1549. Sengoku Jieitai 1549 is a live action movie, based on a Japanese Manga of the same name, about a unit of the Japanese Ground Self Defense Force that accidentally travels back in time while testing equipment to protect military vehicles from electro-magnetic radiation. Traveling to feudal Japan, the unit finds itself in the middle of a battle, part of the Waring States period of Japanese history. While most of the unit returns to the future, the leader of the formation remains behind and begins to change the past, causing disasters in the future. In the future, a new team is assembled to go back in time, find the rogue commander, and stop his actions, thus restoring the future timeline. I already own a model of a T-90 tank used in the movie which wears standard JGSDF markings, making this an easy and cheap choice for the campaign.
I will keep looking for other possibilities.
