How to Supply Land units during war (White Giant)

I'm new and have read a ton but I'm having trouble re-supplying my two Attacking land divisions. I have two supply units, one each for each attacking divisions. The supply units are saying they are replenishing the attack units but nothing is being replenished or replaced. I have even brought the attacking units back to bases but I am not able to resupply them nor replace lost equipment within those attack units. I'm lost now and getting ticked. HOW in the world do you replace and re-supply your attacking units???

You probably need more than 2 supply units. They have other jobs to do too. Check you have the stuff your land divisions need so the supply units can take it to them.

In the last resort, send the land units back to base as you did, dismantle them and rebuild them again. That way they should rebuild fully supplied.

Yeah the supply units were at the same base as the attacking units for like 10 days and nothing got resupplied. By the way I went to bed and woke up this morning and my two attacking units which I pulled back to a base in my country were gone. Poof! Vanished. I appears I have their equipment still but it's listed as "inactive" and I haven't been able to "reactivate" them. I tried to "set up" and new land unit but it won't let my use those vehicles or tanks and I am getting frustrated with this whole thing now. GGGRRRR!!!

The two supply units ghosting them are gone as well and I can not "reactive" the "inactive" weapons. Is there a time limit if they go "inactive"? How do they just vanish automatically?

Maybe you don't have enough mid level managers to keep them activated and your army is deactivating because of it.

Gringo is probably right. And the automatic systems will de-activare your army if your economy cant support them too. Check your newspaper for the last months, it should tell you, or automated systems page has a link that shows all actions taken by the automatic systems.

reduce garrisons or more supply unit
I have like 30

I got the supply part all figured out. Thanks : D
