mangonel with 6 hexagons range?

[rennodm]

In my last game as Egypt, total 5 players, 2 continents, I got the impression that at least some of (AI)Carthago's mangonels enjoyed a 6-hex range.
Is it at all possible, and/or restricted to (selected?) AI-controlled nations?

If available to human players, how can I get access ?

Also there is a unit ability that gives +1 range. I think it is Marksmanship and first requires taking Eagle-Eyed (may have the names wrong).

Tks, this clarifies. I'll try to implement same to my benefit.

City Towers also give +1 range. They work well on defense. Not sure what the range modifier might be for a hill city.
