A defensive fighting position (DFP) is a type of earthwork constructed in a military context, generally large enough to accommodate at least one person.
a Trench would be more of Ditch but all trenches start from a individual fighting position and work their way up in stages, which are then connected with other positions to build a trench.
armies dug ditches and fought each other
Trenches were large ditches (hence "trench") dug into the ground. Soldiers would group together in trenches during battle and operate out of them as they attempted to take the enemy trenches.

Soldiers often take cover in a "foxhole" during a battlefield situation. A foxhole is a small, often shallow pit dug into the ground that provides protection from enemy fire and shrapnel. Additionally, soldiers may use trenches, which are long, narrow ditches, for more extensive protection and movement across the battlefield.
ditches dug and built to control flooding and to better water more land
Trenches were dug to protect the soldiers from enemy bullets.
A dug ditch is a narrow excavation in the ground, typically created for the purpose of drainage, irrigation, or to delineate property boundaries. Ditches can vary in depth and width, depending on their intended use. They are often lined with vegetation or materials to prevent erosion and may also serve as habitats for wildlife. Additionally, dug ditches can facilitate the flow of water to prevent flooding in surrounding areas.
