This is an interesting unique. The stat that may jump out at you is its disappointing 17 Combat Strength- 3 less than the Warrior, which it does not replace, and less than any unit in the game with the exception of the Scout. However, it has some things going for it. First of all- its 3 Movement, more than any melee unit all the way until the Atomic Era, as well as its 3 Sight range. This makes it as effective, and slightly more survivable, than the Scout; additionally, it has the standard melee +10 Combat Strength bonus against anti-cavalry units, which makes it effective at clearing out barbarian camps, unlike, say, the Okihtcitaw. Babylon especially wants to scout, and be on the lookout to claim as many tribal villages as possible to pick up some early Eurekas. Finally, it has a whopping 17 Combat Strength bonus against all cavalry units, whether light or heavy. While not especially suited for conquest by itself, the combination of its unique traits makes the Sabum Kibittum an excellent defense against cavalry, even more so than the underpowered Spearman. Its bonus makes it almost as strong against cavalry, it is not only cheaper but available earlier as well, and its greater Movement allays the main flaw with anti-cavalry units- the inability to catch up with the cavalry it's meant to defend against. It could perhaps supplement an invasion and deal with pesky cavalry harassing your main army of Warriors and Archers, or use its Movement to snipe an irritating ranged unit.
