wow, what a thread this is!
I can't play SH3 due to loss of computer so I haven't come here often.
My questions are: How would a sub (German or American) pump water in the sub to the outside. For example when taking on water from an explosion.
Also when a destroyer pings for a sub wouldn't the first thing the ping hits underwater come back? How would the radio man at the helm know if it is a sub or not?
