The headline says something important, although if you were paying attention you already knew it because Gen. Odierno said in 2013 that fighting sexual assault should be the "primary mission" of the Army. That would be most perfectly done by disbanding the Army, which would result in a 100% decrease in sexual assault within the service.
So it's interesting that the #2 priority is... shrinking the Army. This is described in terms of "balance" and "skillful transition," but explicitly it is about "declining budgets." (The other most effective thing we could do -- eliminating units in which people who are sexually attracted to each other serve together -- is a non-starter for this administration, which is running as hard as it can in the opposite direction for its last two years.)
It's curious that, with Middle East on fire, our Army's top two priorities are these two. But if we intend to pass the problem off to Iran by helping them expand their regional hegemony and erect their nuclear umbrella, I suppose we won't need an Army capable of going to the Middle East with any superior force. If we go at all, it'll be as partners with Iran. Indeed, in Iraq, that's already the role we are playing.
