Yes, just the equipment - that makes sense. Easy to forget that.
To clarify the figures in the production pool a little more:
We can group elements within the production pool into two groups: a) those elements that are sitting in the pool already attached to the relevent manpower they require, and b) those that are just equipment in crates.
So am I right in saying that group a) would include: all AFVs. All aircraft. The numbers you see in the pool of these essentially have crews sitting in their machines waiting to go to the front.
and group b) would include: all artillery including AA and AT. All infantry squads, whether pioneer, grenadier, motorcycle, or whatever.
Two elements I would be unsure about would be support, and vehicles. Do these, or do they not, when sitting in the pool, already have manpower assigned to them, or are waiting for manpower?
