Cities, mountains, and ports favor a delaying defense

Taiwan has prepared for invasion throughout its existence, which gives an attacker a defensive system built around that specific threat. Many of the flat areas that appear suitable for invasion are heavily urbanized, making rapid movement vulnerable to slow, costly fighting through streets, concealed positions, and traps. Mountains impose further obstacles, with ports on both sides offering possible routes for support. Allied amphibious and support ships carry their own unloading equipment and could use damaged port facilities or beaches to bring in supplies.
