I think this LST unit would restrict amphibious invasions too much. In some cases, it would make an amphib landing impossible.
right because in many cases it was impossible. The idea of invading some area 1,000 miles away does not make sence. Invasions can only be supported by short travel from supported areas that you previously staged.
The US player does a direct invasion of france or Norway, though it takes 2 turns its still done and not realistic. So in order to invade Italy, the allies must stage first in Algeria, Tunisia or Libya. Gibraltar is too far, but they can get to southern Europe.
remember these are optional rules…
