'Archers' in the Bible

If the king is angry and says, Why did you go so near the town for the fight? was it not certain that their archers would be on the wall?

So the man went, and came to David, and gave him all the news which Joab had sent him to give; then David was angry with Joab and said, Why did you go so near the town for the fight? was it not certain that their archers would be on the wall? who put Abimelech, the son of Jerubbaal, to death? did not a woman send a great stone down on him from the wall, putting him to death at Thebez? why did you go so near the wall?

And the archers sent their arrows at your servants from the wall, and some of the king's servants are dead, and among them is your servant Uriah the Hittite.
