I agree with changing the uniform camo for bravo and charlie to the suggested patterns for two reasons.
#1 - Realism. The us senate has ordered that UCP be discarded for the safety of the US Army soldiers [2014] and the most likely candidate for the new camo is the OCP and MARPAT is what the marines use [variant depending on geographical location/climate]
#2 They both suit the terrain much better than the current camos we use.
