'Men of War' in the Bible

This is the reason Joshua circumcised: all the people who came out of Egypt, who were males, even all the men of war, died in the wilderness by the way, after they came out of Egypt.

For the children of Israel walked forty years in the wilderness, until all the nation, even the men of war who came out of Egypt, were consumed, because they did not listen to the voice of the LORD. The LORD swore to them that he wouldn't let them see the land which the LORD swore to their fathers that he would give us, a land flowing with milk and honey.

All your men of war shall march around the city, going around the city once. You shall do this six days.

All the people, even the men of war who were with him, went up, and drew near, and came before the city, and encamped on the north side of Ai. Now there was a valley between him and Ai.

It happened, when they brought those kings out to Joshua, that Joshua called for all the men of Israel, and said to the chiefs of the men of war who went with him, "Come near, put your feet on the necks of these kings." They came near, and put their feet on their necks.
