True if you are firing the rifle for the first time on the rifle range. You could start with whatever it took to put a round on paper at a certain range. As far as the term
"Battle Sights", as I recall, that is the setting you use in a combat situation when the distance of the potential target is unknown. Take the article you wrote for the Summer 2012 GCAJournal about Hector Cafferata. In a "battle" such as Pvt. Cafferata found himself in, most of his shots were up close and personal. As Hector said " you just put the front sight on them, pulled the trigger, and down they went". No time to worry about changing sight settings. Long range shots would be left to snipers for the most part.
