>>3042165>back to [the old times] when hills were extremely important battlefield locationsThey still are, anon. Even the Korean and Vietnam war were filled with stories of hundreds of deaths over nearly worthless hills, because the elevated position was invaluable for positioning alone.
One of the ones that was famous in the Vietnam War that caused the phrase "Choosing which hill to die on" to catch on was the Battle for Hamburger Hill, which the American military fought to take it with a frontal assault using the 101st Airborne, lost nearly a hundred men, then immediately abandoned it after taking it because it wasn't worth much. The resulting controversy at home popularized the phrase in the 1970s. You don't hear much about hill battles anymore because by and large, the first world hasn't fought a war in a location with hills of merit for fifty years.
