Recognizable by their green-panel shirts, these soldiers are highly trained and highly knowledgeable, perhaps more so than any other occupation in the Star Army. Wearing green is a great responsibility.
Science Officers need to know science, physics, ect, well enough IRL to allow their characters to be able to use it in game. This should require considerable work on the player's part, and there should be few science officers because of this, but ultimately that should be why science is the 'fast track' in Yamatai's Star Army. The amount of things a science officer can do in this setting is staggering! Ship design is probably the most popular but there is also forensics. Bypass razorwire by throwing a blanket over it, Remind the captain that trying to put out an electrical fire with any fire extinguisher that uses water will only cause more damage, navigate the ship when it has been damaged by putting on a space suit and using a scanner, find out where the assassin fired from by looking at the impact angle and depth of their bullet holes, stop a sulfuric acid leak with a chocolate bar, and generally look for ways to apply science skills to the problems being faced by the crew. Most of the time tech inconsistencies and super-science shouldn't even be an issue.
A good science officer should be the go-to person for solving the ship's problems.
