...to add to Hydro's post, when you PCS overseas you should get two shipments. Unaccompanied baggage and your household goods. Unnaccompanied I think runs around 300-500lbs allowable (may depend on rank/destination) and is supposed to arrive within 30 days. This is typically things you will need quickly upon arriving at your new duty station...ie, kitchen stuff, sheets, blankets ect. You can ship your pro-gear with unaccompanied and it won't count against your weight allowance. And you can get creative on what counts as pro-gear. Two trips to Kadena and my unaccompanied has always arrived within 2 weeks.
