Phong Nha Valley
4.4 km river valley with jungle-covered hills, building clusters in the north and large low-detail areas. Plan operations on this 4.4 km Arma Reforger map in TacOps.

The 4.4 km map is hilly ground (10 to 210 m) with a river running from the southwest corner through the centre to the east edge. Dense jungle covers the north edge, a northwest patch and the central river bend. The 477 buildings mostly sit in two clusters near the north edge; roads are nearly absent. Most other land shows only blurred, pale ground imagery with nothing placed. The author calls it a detail-oriented Vietnam War map, early work in progress. It suits small foot patrols.
