Can you help me understand accompanied PCS overseas?

unless its considered a hazardous duty station I.E (Kuwait, Turkey, and select locations within Korea) you will go accompanied

It depends. You can go accompanied or unaccompanied. The tour length for unaccompanied is 1 year.
- Korea has accompanied tours for the last few years.
- Germany is almost always accompanied.
- Japan is mostly accompanied.
- all places have limits due to EFMP unique requirements.
- you can volunteer to go unaccompanied for a shorter period due to family needs.
- there are other lesser included cases in other countries, but these will be the main foreign overseas tours.
- HI and AK are "overseas" tours and are common enough.
- all others are case by case l(talking PCS not an operational or combat deployment): Poland, Netherlands, Belgium, France, Norway, UK, all of those are accompanied to my knowledge
- there are still others I don't know about, but these lesser included cases are usually for more senior NCOs, warrants, and officers.

If I understand your question. The bases have nice housing, schools, hospitals and clinics, PX and Commisary and all other infrastructure needed by Service members and Families. Go online and look at oversees bases.
