Can it be done? I managed to squeeze a single troop module into a hull just small enough that my destroyers could carry it through jump points, hoping to get an engineer brigade piece by piece. No such luck. So I built five of them. Still wouldn't pick them up. I wound up making another troop transport class, but I'd really like to know if there's a way to do it.
Also, can you split a marine regiment into five companies, or do you have to build them company-by-company in the first place? If you can split them up, how?
