I know that the Imperial Guard is reliant upon the Imperial Navy for transportation, but I'm not entirely clear how the Navy goes about ferrying troops around.
Does the Imperial Navy use dedicated troop transports or do they simply transport troops on various warships?
Other than a Barracks, what components are essential to making a 'complete' troop ship?
If a ship has multiple Barracks components, does the bonus to conducting/defending against H&R/boarding actions stack?
