11) Don't count on what you don't yet have

Don't over-rely on troops produced mid-war in Hearts of Iron IV. Learn why focusing on pre-war units and managing wartime challenges is crucial for success.

Alright, let's talk about something super important for managing your production in Hearts of Iron IV, especially when things get hairy: Don't count on what you don't yet have. This might sound a bit counter-intuitive when you're trying to build up your forces, but trust me, it's a key piece of advice.

Look, I'm not saying you should just stop producing units once the war kicks off. Far from it! You'll absolutely need to keep churning out divisions. However, you need to be realistic about what you can actually expect from those wartime productions. The reality is, you'll probably have way bigger priorities demanding your attention. Think about it:

• Dissidence: You'll have to deal with internal unrest, which directly impacts how bad partisan activity is in your newly conquered or occupied territories. Ignoring this can lead to major headaches.
• Reinforcements and Upgrades: Your existing troops will need support, and you'll want to upgrade them to stay competitive.
• Loss of Industry: This is a big one. Enemy bombing raids, losing provinces, and dealing with that internal dissidence can seriously cripple your industrial capacity (IC) for extended periods.

What this all means is that the shiny new divisions you've ordered might never actually get finished or deployed. They take a long time to build, start with zero experience and organization, and crucially, you can only deploy them in territory that was legally yours before the war even started. So, if you lose territory during the war, those new troops can't even be placed there!

And here's another angle: think about your enemies. A country that isn't at war with anyone has to prepare for *everyone*. But a country that's already fighting someone? They're going to focus their attention on that active aggressor. This means if you're not the one being actively attacked, you might have a bit more breathing room, but it also highlights how much a country's focus shifts when war is declared.

So, the big takeaway here is to consider the units you have *before* the war breaks out as your reliable fighting force. Anything you manage to produce *after* the war begins should be treated as a welcome bonus, but don't base your entire war strategy around it. Plan for the worst, and anything extra you get is just gravy!
