The forty-mile (64 km) Suwalki Gap cannot be considered a gap in the sense of natural boundaries, such as rivers, coastlines, or mountains. Travelling through this area last October while studying NATO units, the author discovered that the aforementioned corridor is an open rural region, covered primarily by flat farmland, interspersed with forests and small villages. A large part of the territory has
ideal terrain for tracked vehicles.

The Suwalki Gap separates the Kaliningrad Oblast from Belarus, where several thousand Russian soldiers are currently based, who, it seems, will soon be stationed there permanently. Suwalki, incidentally, is the only route by road or rail to reach the Baltic states from Central Europe and Poland - NATO's most geographically isolated (vulnerable) part.
