I try and click on the brigades from the deployment list, but I can't click on anything to deploy it.
I want to clarify that choosing the brigade in the deployment pool first - and then trying to decide which out of dozens and dozens of possible choices is the actual INF you want to attach to is "the nightmare way of doing things". For sure you get brigade on other INF you never meant to.
MUCH BETTER, you click on the division sitting on map you want to attach something to, and then click its Attach Brigade Button (the + sign) and that will then show all brigades currently in deployment pool that are attachable to that division (including brigades currently locked - meaning they were recently detached and can't reattach for 7 days).
The only important things to watch for:
1) Your unit does not have Offensive Supply (can't attach until OS is ended).
2) The unit you want to attach something to is in the same political region as is the brigade. As regards new brigades, the Political Region is "German owned province" and is identified by a German flag only when clicking on province.
As regards other brigades detached in in other political regions, they can only be reattached in province of identical political region.
EXAMPLES:
a) brigade detached in SU province that Germany controls shows a SU flag under German flag, and can only be reattached in identical political reion.
b) Brigade detached in Ukraine can only be reattached in Ukraine.
c) Brigade detached in SU province that Hungary controls has SU flag under Hungarian flag, and can only be reattached in identical political region.
SO - watch for the province flag-combinations, that your unit has no OS, and that brigade is not locked for 7 days. That's all.
