Make weapons reactivation take same amount of months as war declaration

Make weapons reactivation take same time as war declaration so you are prepared since, you know, whenever you make a new unit of some kind they get deactivated 100% and you have to wait a whole year to get them up and running again.

Weapons have for as long as I've been around have always been reactivated at 10% of the available units in stock. I.E. if you want 400 interceptors to reactivate each month you need 4000 interceptors in stock (not deployed in air wings).

I've never viewed this as unreasonable. It's easy to deactivate something but more difficult to drag back out of mothballs and into active service.

If you plan a war, make sure you start activating some time ahead of the start of such a war.

Deactivation allows players to reduce the cost of the army.
but there are disadvantages too.

if you want to remain 100% flexible keep your army fully active.
