Switzerland

Switzerland is a unplayable (★) faction that is neutral in every scenario being A.D 1865 and A.D 1914

A.D 1865
Switzerland borders France, Bavaria, and Italy which means if it sides with the monarch states, they can get jumped by France and Italy as it only has Zurich (City lvl. 5) and a rifleman unit so they're practically a stepping stone.

A.D 1914
Switzerland borders France, the German Empire, and Italy. This time it has a bigger defense having two units and a fort but the other countries also have a bigger defense and can quickly pound Switzerland into submission, should any country declare war on it.
