Unless you called it a submersible I would expect torpedo tubes. I can't  advise a forward hatch. That will make the forward armor much weaker, and that is a very bad thing. The only troops that warrant a sub are special forces, and they should be approaching the shore and their targets in mini-subs. That's how it works IRL.

Subs aren't meant to be troop transports.
