ARVN Umbrella Trooper

"Since the ducangers ruled South Vietnam as of now, the ARVN Umbrella Troops are here to infect us all, and the Undead Alliance, including the Umbrella Corporation, should be ashamed of South Vietnam for stealing out the name 'Umbrella' to such inept ARVN guys out there. Why? Because South Vietnam went rogue against the Grand Alliance, the Coalition of the Red Star and the Global Liberation Union for obvious reasons."

--Su Ji-Hoon, Sickness Crawls Upon Us
