The Confederation of Dixie did not form a permanent army to protect them during their formation. Each State supplied a force to act as part of a combined army that would represent each State for Confederation-wide deployment. It was just such a Confederation force that supported Australia when it came time to stand against Chinese expansion, and that helped deal with the final Rogue AI nest in Singapore. This practice has remained true for centuries. There is still no permanent Confederation army, but a rotating sequence of State units continue to work under the Confederation flag throughout their lands on Earth and their various colonies in the stars. This results in each Confederation force being uniquely different from all others, and foes rarely know what exactly to expect when facing one. This can be a weakness and a strength, and sometimes both at the same time.
