A very good short story published in a military science fiction anthology - possible 25 years ago. Protagonist was a female officer trying to get her ragtag platoon through the jungle. There had been a world war between the Muslim countries and the rest of the world - largely in the southeast Asia region.
Story featured high-tech gear/vehicles and great writing. For example, I seem to remember the skin of the Armored Personnel Carrier (APC) they had able to change to fit the surrounding environment. There was a particularly deadly river crossing that was a real challenge for the group. I'm thinking loosely modeled on Homer's Odyssey - a military unit trying to get home or at least to the nearest friendly base.
Can't remember the ending but presumably the officer and her platoon end up good. The writing was so good that I'm thinking the author has been published more since then.
