Operation Unterstützung is an operation that had began in the mainland of the Glorious Empire. It was a military action performed by the Stahlhelm Army, with assistance of the newly-formed Vietnamese Defense Force, to deliver relief supplies and rebuilding to the war-stricken nation.
Credit to @Bigelol234 and @ShadowWolfyMoony9118. This was the Vietnamese military's first action since the Vietnamese Imperial War. And despite being met with controversy, the VDF has so far performed well in Operation Unterstützung, providing help when a nation so desperately needed it.
