>>2771373>Dugouts are usually made as fortifications, similar to trenches and tunnels.Primitive dugout with some logs, easy to conceal the entrance, can sleep soundly and even cache things. A sufficiently concealed shelter under a sufficient layer of dirt or stone, such as a cave or tunnel or dugout, can prevent detection from satellites, aircraft, thermal sensors.
The thick layer of Earth can also protect from strikes from drones, jets, artillery, mortars, helicopters, and so on. Tree cover can conceal you from indirect angles and even satellite imagery, but not from drones or aircraft positioned directly above, especially with thermal sensors.
