In general the Fenkhu, Yamhad, Sinai, Retjenu and Aber Nahara rosters have been spread out a bit as the units do not really correlate with the realms they originate from. And because I am a pedant the “realm” Aber Nahara is split between this category and Mesopotamia.

-Retjenu urban barrack, urban troops in coastal and major cities also in Alašia
-Syrian range, Syrian archers in the north
-Shasu camp, shasu troops in the Sinai
-Habiru mercenary Inn, light troops in major settlements south of yamhad
-Habiru camp, light troops in minor towns south of yamhad
-Ahlamu centre, desert units in big cities east of Damascus
-Ahlamu camp, desert units in small towns east of Damascus even up to urartu and southern Mesopotamia
-Aramean centre
-Alashia raider camp, select Aegean and sea people units on Cyprus

Canaanite factions are less capable to field huge imperial armies but the cities are quite capable of supplying stationed troops. So instead of reducing the administrative burden they can build defence centres which drastically reduce upkeep of troops in the region. Outside of Canaanite territory these Garrisons are staffed by mercenaries and provide their benefits to them instead.
When damaged they reduce Influence in adjacent regions, reminding the locals that your power can be broken after all.

Bay is a schemer and diplomat not a warlord. His troops are varied and he has access to foreign units but he is dependent on major settlements and ports. His troops lack staying power.
-Militia barrack
-Militia range
-Mercenary Inn, habiru, ahlamu, and other troops
-Port tavern, sea people and Egyptian troops from port towns
Also he can build the Divsional HQ, tho the troops provided are slightly less impressive.

Irsu is supported by his Henku and Shasu kinsmen, the professional Sabu Nagib soldiers and rebellious rabble.
-Henku palace
-Sabu Nagib barrack
-Hupshu barrack, weak troops in all settlements
-Sabu Nagib colony, few Sabu Nagibs in minor settlements with a malus
