I just returned from northern Iraq serving as a military transition team member.
15 months of training and deployment was long, but it was an outstanding experience to understand my role as a current Army officer. I believed the officers served in Iraq as a MiTT will be better prepared for future deployments and will do well in next duty position.
Here are some examples, First, living with the Iraqi Army day to day, I learned how their culture work, how they think and how they operate, also I pick up their language very fast. End of my tour I was able to read and ask simple questing during missions. This was the best culture training that Army provided.
Second, I witnessed the good and bad operations from coalition partner units. Observing from the outside of the units, it helped me to see and feel what looks right.
Therefore, the experience that MiTT member will goes through will better prepare for future deployments.
