Transport/Sub Non-Combat Rule

[TexCapPrezJimmy]

Can an unescorted transport unload its cargo in a Seazone containing only an enemy sub during non-combat? For example, the UK is reinforcing London with a single loaded transport from Canada but there is a German sub in Seazone 109.

I suspect it does not block in non-combat movement, but if it was an amphibious assault it does block, correct?

Thanks!

Per the Alpha+.2 rules, only amphibious assaults are blocked.
