Why are three tribes being mentioned by name?

Joshua 1:12 (ESV)

12 And to the Reubenites, the Gadites, and the half-tribe of Manasseh Joshua said,

These tribes wanted to live in the land on the eastern side of the Jordan River (Numbers 32:1–42), and they were allowed to do so by Moses (Deuteronomy 2:26–3:17) on the condition that they also fight with the rest of Israel to capture the land to the west of the Jordan river. They are now being mentioned by name since the military venture about to begin is not the exclusive duty only of the west-bank tribes but an all-Israel operation. All Israel is to bear its burdens, suffer its losses, pay its prices, and share in its victories.1
