Units have no weapons

Afte war, my attack and bombing wings are at 0 with their weapons. I have houndreds of planes in stock, why doesen't it replenish the units with new bombers, drones, etc.? Do I have to make it manually? If yes, how? And if not, how does it replenish then?

I already thank you all for your answers!

Check to make sure your supply units are still there, and if they are still stocked.

They are

I would try rebuilding them if you've exhausted other avenues.

That's what I do every time... It is so annoying, to rebuild a unit, all the training is lost and it gets expensive...

I have noticed I seem to get that in countries where I am upgrading units and either the ammo or weapon upgrade runs short.

FYI the training does not get lost. It does however mix with lower quality units providing you with a blended quality the next time you reassemble.

As an example if you have 450 quality units and disband them and there are no lower quality units in your country to mix with. They will remain 450 quality units. And if they do mix, all the lower units will rise in quality.

Just ignore that warning.

Alright, thank you!
