An Earth forces Commander

Ah yes you are an Earth forces commander.

You joined the Earth forces when you were of young age, being proud to serve your planet and protect Democracy from Mars.

You joined up 5 years into the war as a Grunt and thankfully never saw heavy fighting.

You have just been recently promoted to commander which you are immensely proud of (it also helps that it pays well)

What was the reason why you were promoted?
