Madam Chair, thanks for that question. It certainly is an interesting question.
As far as I'm aware, no study is being done right now to look into those possibilities. I wouldn't want to speculate on the type of personnel or the pool that would be drawn from for each. Perhaps something that would require more study would be to look at the U.S. corps of army engineers, which is an entity distinct from, say, the U.S. Army engineers. Each provides a different level of combat support.
