Can you wear a combat patch for a unit you supported?

If you are not still a serving member, it really doesn't matter. I still have the uniform in the photo, but I never expect to wear it again, so how does it matter what I am authorized to wear?
If you were told to wear 49th QM, that is what you wear! Dead Simple! Follow ORDERS.

to the best of my knowledge you are only authorized the patch of the unit you were assigned to. for example i am authorized 2 different patches for wear on the right sleeve, 3cav and 1ad, but I am not authorized to wear the patch of 18abn corps which 3cav was attached to and operated in support of. or whatever un command 1ad operated in support of.

I think the one you had but I have no real answer my friend just show pride in the one you had . It sounds like to me you guys did a great task and that's all that matters.

U can only wear the combat patch of the unit you wear assign too and and you will get a Memoradum from the commanding officer of that unit stating your right to wear your combat patch on your right shoulder..

If you served in theater with another unit besides the 49th QM, then you are authorized to wear that patch as well. Your choice.

AR 670-1 is the source to use when having questions about what to wear on a uniform. Just because a person supports another unit is admirable, but when insignias appear on uniforms that are unathorized, stories can be told which are not true.

It is even more so with civilian employers. Embellishing a service record is dimly viewed by most employers. AR 670-1, read it and it will make sense.

There are a couple things you need to find out and your chain of command can help with the answer to your question. First the Army Regs. Are clear as to weather or not you qualify to wear a combat patch! You need to look it up and see what it says. You must meet certain requirements and time periods to be allowed to wear a combat patch. Then you must be directly assigned to a unit that is within a combat zone for a specific time period. The regs. are very specific and you must meet all the requirements in order to qualify to wear a combat unit patch. The one thing I read that you wrote is that there are soldiers wearing different combat patches from the same unit! This is definitely wrong. You either qualify or not,and if you do your unit would only be able to wear one patch for the entire company. There is no way that you would qualify for more than one, unless you left the battle and were CPS'ed back to the states, and were ordered back into the area of operation in a different area and command. And it would have to be a second or third tour in country under a different command and unit. This would explain why some soldiers wore different combat unit patches. In other words, different unit assignment in country and actively engaged in combat action with that unit for the required time frame, and secondly to be eligible to wear a different combat unit patch you would have to be assigned to a second or third or more tours in country and involved in combat actions with that unit for the prescribed time frame. And lastly you can only wear the most current combat unit patch for the unit of which you were engaged in combat with. You can not wear one on one uniform and another on a bother uniform. It's the same as wearing your unit patch that you are currently assigned to. And the way you know you are allowed is the fact that you would be issued orders to the fact. If this doesn't help, look up your Army Regulations and they will set you straight. Don't ever assume that you are untitled to wear any patch or decorations before you are issued orders stating that you are qualified to do so. If you are caught wearing any decorations without orders, you will find yourself in big trouble. Don't be what we used to call a PX Soldier. This is a soldier who goes to the PX and buys all the new shiny badges and wears them on his uniform as he figured he was in the Army, so that entitled him to be able to wear them! You will always receive orders and they will hold a formation to award those who have earned the right to wear any and all awards of all types from medals, combat patch, CIB, EIB, and every other award you have qualified for. Just remember that you can only wear the most current and approved awards. Some awards are not permanent in nature. This doesn't mean you don't have it ,but that some awards are not transferable from one unit to the next. Some awards are unit specific and can only be worn with the unit of issue. Bottom line, in in doubt ask your chain of command and read your Army Regulations covering awards.

Yes

See your unit's task organization chart. Who was the higher headquarters. Of course you supported a lot of other units but the units that are outlined on the org chart will tell you which ones and how many different ones you can wear. I was in 2AD but fell under 18th AB Corps. Was told I could wear either but wore my unit.

Prior to 2005, maybe. After, no.
