Is it okay to wear the deployment OCP when you've never been deployed?

Yes it is, there is no regulation that states any soldier regardless of rank can't wear OCP uniforms.

Hey PFC, how about taking some initiative and find out by reading the regs. I know several NCO's who have not been deployed yet, dont make them bad leaders or any less of a leader. Police down not up- believe me when i say it, there is someone watching that young Sergeant and if he is wrong his fellow NCO's will certainly correct him.

Since you were issue OCP at basic I'm assuming you've been in all of like 4 months. You should probably keep the stupid questions the minimum. With less than a year in service you should be seen and not heard.
It's called Multicam, for starters. And it it authorized for everyone to wear until 2018, along with the ACUs.
You can wear any of the 3 uniforms as you see fit until 2018 when they are phased out.
You coulda Googled that bro.

Things change all the time but if someone outranking you is wearing it properly then it's more than likely authorized. I remember all the different work uniforms I've worn and still have most of them. Korean issue cotton, Vietnam issue jungle Fatigues and Tiger Stripe, Permanent Press (Hated These), BDU's, Chocolate Chip Dessert, Tri-Color Dessert, and Arctic White. There's been a bunch since then.

This is ridiculous

Yes during the transitional period he can wear that uniform but he has to wear the desert boots, desert belt and tan shirt we wore with ACUs

In February, my unit went on a week long FTX to Poland (I know that a week isn't very impressive, but hey, what am I gonna do about it?). As part of our field preparation, there was a mass exodus to CIF, where more than half the company were issued either multicam, or some variation of OCP. I personally was issued the old school multicams, fades and all.

So yes, he is authorized to wear them, deployment or no.

Yes. And they are way more comfortable too.

So the new uniform for the army is the OCP. Anyone who deployed to Afghanistan in like 2010 or later was issued Multicam.

OCP and Multicam are similar patterns. There is just enough difference for it to be considered two different patterns.

The way you can tell the difference is the pockets on the sleeves. The new OCP are zippered instead of the velcro. And these outfits are available for purchase.

Since they were just put out as being the new uniform last year, there is a wear out date. I think it's like September of 2019 for people to wear the ACUs or Multicam. There are also regs that talk about what parts you can still wear with the OCP or multicam. Because the new OCP will have a greenish shirt, belt and boots.

Edit: I think I'm referring to "Multicam" uniform he was wearing.
