Character mistake: Soldiers leaving the foldable stocks of their weapons folded, despite knowing that they are going into a combat situation. Particularly affects the MP-40 wielded by the Germans in WWII movies, but also some modern examples like the MP5 and the G36. Automatic weapons are difficult to control at the best of times, there is no reason a trained soldier would deprive themselves of this extra bit of accuracy.
