I would say MSM.
My story is first deployment, not my unit, got an ARCOM and did go out of the wire for other than party pic missions. My NCOIC an E-6, I'm an E-5, doing the same job I did, got a Bronze Star. Other guys that were actual squad leaders and went out the wire every day got ARCOM's. My NCOIC only went out the wire on party pic missions, safe runs.
Second deployment, my unit, put in for the Joint equivilant to an ARCOM, downgraded to the Joint Achievement Medal. My soldier under me got downgraded to the ARCOM from MSM. My S-2, OIC received a Bronze Star. The reason for downgrading was the reverse quota thing.
