Vash Color
Because the nation of Tiran is based on a desert planet, the main color for the TIran armour would be a desert sand color,
Also, another main color for the Tiran nation is orange, i've decorated the armor with orange decals
Even though this is supposed to be a marine in the futuristic world, i've decided to arm him with a present day primary (M2000 rifle) and secondary (1911) because these firearms are capable to be an effective weapons for a period of time (personal opinion)
