These are great and detailed answers to my simple question, what 'constitutes a pocket' in regards to SC titles.
Yeah, in a lot of the ancient and venerable board wargames, (Avalon Hill, SPI, etc), even with out detailed supply rules, units that couldn't trace a route except through a zone of control to a capital or maybe another significant town etc, would be judged 'isolated', and a time mechanism would kick into place before they were eliminated. In some games, this route could take the most insane path regardless if there was a supply mechanism or not.
Now this could provoke grognards to argue why this could be so. One pretty good argument I heard was that there is a psychological impact on the forces that were cut off, not just supply considerations.
Anyway, much food for thought and reparte on this subject.
