War Era Tools

A small collection of tools that read the War Era API for things the in-game UI doesn't make easy. Pick one to begin.

Irish Military Units

Every MU owned by an Irish citizen, in Ireland, with a majority of Irish citizens. Filter by whether they have open slots, and see who's already inside.

How MUs are selected

Owner nationality — the MU's owner must currently be an Irish citizen. Owners who've migrated away get filtered out, even if they founded the MU.
MU country — when the MU exposes its own country (under countryId, country, nationalityId, or nationality), it must be set to Ireland. MUs without any country field skip this check rather than being dropped, so missing data doesn't wipe the list.
Member majority — at least half of the MU's members must be Irish. MUs with a mostly foreign roster are dropped even when the owner is local.
In the expanded members list, Irish citizens are marked 🇮🇪 and non-citizens are marked 🌍 and dimmed. The Irish stat on each card shows the ratio.

How this works

Production bonus has up to four components. Strategic resources and regional deposits are flat country/region facts; the two +30% bonuses are gated by the country's industrialism lean — a signed integer the game exposes via the warerastats data feed (range −2…+2 in current data, with 0 = neutral). The gating is asymmetric: industrialist-leaning (ind > 0) countries grant the +30 on their specialised item; agrarian-leaning (ind < 0) countries grant the +30 on matching regional deposits; neutral (ind = 0) countries grant neither. Each lean grants exactly one type of +30%, never both.
- Strategic resources — the country's productionPercent, fires when the item matches the country's specializedItem. Independent of industrialism.
- +30% Industrialism (specialisation) — fires alongside strategic resources only when the country is industrialist-leaning AND specialises in the item.
- Regional deposit (the deposit's bonusPercent, typically +30%) — fires when the country does NOT specialise in this item AND the region has an active matching deposit.
- +30% Industrialism (deposit) — fires alongside a regional deposit only when the country is agrarian-leaning.
Industrialism is read directly, not inferred. The signed integer comes from the warerastats companion endpoint. If warerastats is unreachable, the tool degrades gracefully: industrialism defaults to 0 for all countries.
Income tax is deducted from workers' wages, not from the owner's share of production. So whether tax directly affects you depends on whether you actually work in the company.
You work here (badge shown on the card): ranking uses your take-home: (1 + bonus%) × (1 − income tax%).
No badge: you own the company but don't work in it. Ranking uses raw output: 1 + bonus%.
The percentage on each verdict pill is a relative increase, not a percentage-point change.
Numbers shown are regional/country bonuses only. Company-level upgrades aren't location-dependent, so totals here may be lower than what the game shows on your company.
Not modelled: migration cost, active wars or sanctions, worker recruitment effects of high tax, market and sales taxes, or political shifts.
