So, "11 months and change" is his total for overseas deployment? That certainly puts the "Fifth Deployment" in perspective!
He was deployed with the 160th SOAR. They typically deploy for a max of 90-120 days and if the mission requires it, much shorter. They are world wide deployable within 24 hours. That means they will be anywhere on the globe, combat ready within 24 hours. Always ready! Usually their mission is intense, more intense than the “big Army”, and that is the reason for shorter deployments.
Those soldiers do in three months what the regular Army soldiers do in 18 months.
Despite the fact that the individual days add up to 11 months, this on-again off-again deployment has been going on for 5 years. I can't fault him for wanting to move on with his life (he is married). He volunteered, he did his time, and now he should be allowed to move on. Four deployments, no matter how long they lasted, are still four deployments. No reason he should get a fifth.
