I'm stuck between choosing Green-to-Gold and Warrant Officer School. Do you have any advice on which I should choose?

When I was younger, I was given this but of advice
Stay NCO if you want to directly impact and take care of Soldiers
Go Warrant if you want to focus solely on your job as a technician, yes there is leadership there, but only when it comes to improving the Soldiers in their profession.
Go Officer if you want to have a broad impact on a mission.
The officer is the one who declares the mission and the path to proceed to accomplish it.
The warrant ensures the job is done technically correct
The NCO ensures that the Soldiers are trained and for to accomplish the mission in all aspects of their life, and are responsible for ensuring their Soldiers advance in their career.

Completely depends on what you want to do. There are ups and downs to both options.

Go Warrant. Going green-to-gold will send you on the path to the dark side!
