That I can see. And thinking about it- Archery was a more dumbed down primitive form of artillery. Usually skirmishers (armed with bows or slings) ran up the front of the flank to harass the enemy and pick off infantry to cut numbers so the heavies can break the line.
I realized 1st recon was doing the same at Hoover dam on the ridge to the west of the dam on high ground shooting legionnaires while powered armored infantry and regulars move up the line
@Sn1p3r187 The way I see it, archers were roughly divided into 2: Line Archers and Skimirsher/Ambusher Archers. To use LOTR scenes, Line Archers should be walking artillery as you see in the opening of 1st movie. While Skirmishers are those Dunedain Rangers led by Faramir in 2nd movie, shooting arrows from the depth of forest and ambushing Oliphaunt.
