Is it okay to wear the deployment OCP when you've never been deployed?
Buddy had a great new set from a deployment that wasn't used, it was my size, and I don't plan on shelling out for the new uniforms until 2019.
That being said, I know that although not required, it's kind of nice to know that if I know 99% of the people at a function or gathering will be wearing the new uniform, I won't stick out like a sore thumb so badly.

Operational Camouflage Pattern Army Combat Uniforms available July 1
The Army announced today the release of the Operational Camouflage Pattern in Soldier uniforms. The Operational Camouflage Pattern will be available for purchase in select Military Clothing Sales Stores beginning, July 1.
It was a legitimate question from a subordinate troop. Don't be a freaking tool.
My advice to you is to worry less about the NCO's uniform that he/she is wearing and more about the experience and leadership they are potentially bringing to your unit. Focus on their ability to perform and on the job technical experience that will in turn make you a better soldier.

"Can I wear my green fleece or Universal Camouflage Pattern cold weather gear with the OCP?
Answer: Yes. There is no requirement for issued Organizational Clothing and Individual Equipment (OCIE) such as Wet Weather gear, and Extended Cold Weather Clothing System (ECWCS) items to be of the same camouflage pattern as the uniform worn. Wear guidance for OCIE is established by the issuing command, and all items that have been issued are permitted for wear in accordance with locally established policies regardless of camouflage pattern."
