No reports of a Military mobilization to load those ships.
It could be a general purpose readiness exercise.
It could be preparation for a big Foreign Assistance Program (Venezuela?).
It could be a longer term preparation for a planned or potential Military deployment.
Could be spending money before the end of the fiscal year.
I am familiar with the battalion in question. I almost joined it, I was asked to do it.
It has been top-notch, one of the best National Guard battalions in the country.
