I could only find one reference to the Panama Canal in the rules.
"Only Western Allied naval units may move through the Panama Canal, German, Italian, Japanese and Soviet naval units may not move through the Canal. For game movement and supply purposes, the canal is the only sea zone that connects the two edges of the map board."
In our Detroit Game #5, the question came up whether the Soviets could trace supply through the Panama Canal. A group of Soviet units are in White Sea area and are cut off from all land supply routes. The Italians captured the Suez Canal and control the sea routes around South Africa. The only possible supply route left for this Soviet group would be the Panama Canal.
Would it be a correct interpretation to say that since Soviet naval units cannot pass through the Panama Canal, neither can a Soviet supply route?
