As you may know, the Army is moving from UCP/ACU (and the optional OEF-CP/ACU) to the new Operational Camouflage Pattern (OCP). However, its a four year phase in and soldiers will not have to wear the new uniform until Oct 2019.
SMA Daniel Dailey is cool with that. In the meantime, its wear what you have.
“Presenting a professional appearance is very important to us as Soldiers, but we will not inconvenience or burden you during this calculated transition period. We will still be the most lethal fighting force the world has even known even if our belts or t-shirts don’t match for the next few years,” said Bailey.
