Marble Mountains, Vietnam.
I remember the battles there. Those 2 marines were in the air, while my tank battalion was doing battle on the ground.
I remember those battles well.
A great many friends of mine died there.
Semper Fi.
The locals call them Nu8i Xi-mang, in English, Cement Mountains because the gypsum is mined extensively for cement.Some of the peaks don't qualify as mountains any more, or even hills. That big marble dragon in front of your local Chinese Restaurant may well have been born out of one of these mountains.
