Archer is probably one of the best artillery systems in the world, says Norborg, but it will take time before they are ready to be delivered.

Therefore, he sees the Swedish tank, which is also one of the best in the world, as slightly more important in the package.

- It is an extremely modern weapon with very good protection.

It is expected that it will be able to knock out almost all Russian tanks, explains the Ukrainian correspondent.

German leopard wagons

A number of countries are also willing to send state-of-the-art Leopard tanks to Ukraine.

But it is still unclear whether Germany, which produces the wagons, chooses to approve the countries' deliveries and send its own to Ukraine.

However, that decision is expected to be made shortly.
