Amazon的 APO/FPO addresses - 海外購物

今天要購買的商品出現了這個

Shipping: Currently, item can be shipped only within the U.S. and to APO/FPO
addresses. For APO/FPO shipments, please check with the manufacturer
regarding warranty and support issues

我知道是送美國境內和 to APO/FPOaddresses. For APO/FPO shipments

我想問但是APO/FPO 這是什麼意思呢??
我用翻譯軟體研究好久
但搞不清楚是怎麼回事

拜託麻煩好心人救救我!!
感謝感謝 >_<~
