The two largest retailing organisations (and many other companies) in Finland have special responsibilities during a crisis. The operations will need to continue even in the case of emergencies or war. The crisis operations are practised periodically, too, rather than just being some words on paper.

Many large companies in specific fields (such as S-Ryhmä and Kesko) have a legal obligation to do so, but about 1500 companies contribute on a volunteer basis via a network managed by the National Emergency Supply Agency. The companies participate through ~30 sector-specific pools, which include the Logistics Pool (supply chain optimisation), the Finance Pool (continuity of payment systems and banking services), and the Energy Pool (energy system resilience), among others.

How Finnish supermarkets are central to the country's defence

The chains all have detailed plans to follow in the event of the nation going to war.

@harrysintonen AFAIU the supply chain laws for those two are also interesting: they cannot use same chains. This also applies to their digital tools, so if software is too core to their operations the vendor cannot sell it to both parties. There is lot of preparations and laws going on that people normally don't even see.
