Oh I well remember RockinR's explanation.

About 6-8 months ago he, very very patiently explained Dick's technique to me. He was even able to do so using very small words and he typed them real slow as he knows I am not a fast reader.

Most appreciative of his patience.
In using Dick's technique in SH3 it was a little different because, as Fincuan pointed out American subs aint German subs.
I really appreciate you guys setting me straight on this. It was frustrating seeing INJ sailors enjoying a pleasure cruise.
One other question on a different topic. If I never intend to use the german missions in SH5 1.5 is it really worth getting? What will I get for my precious 10 bucks if I stick with American subs in SH5?
