7/ The latest reform of these lines concerns their continuity and depth. In 2025, many lines simply stopped in front of a ravine, a river, a path, a treeline, or a forest. That is no longer the case. Treelines and forests are cleared over at least 500 meters, rivers are covered with barbed wire, and paths/roads are protected by side ditches and barbed wire, channeling movement. Many lines were standalone in 2025; now there are lateral lines, as well as 2nd, 3rd, 4th, 5th, and even 6th lines in certain sectors.
