How do subs fight subs?

[superman81906]

No matter if my sub is hunting or silent or the enemy the same, I can not target another sub?

Thanks

Subs don't fight other subs. It happened a few times between single subs with deck gun, and a one or two times they even tried (and one time even succeeded) to use torpedoes, but never in the scale the game works, a single str of a sub unit represent more than one sub.

Subs can only be hurt by other subs by moving through them.
