This was announced by Swedish Prime Minister Ulf Kristersson on January 19.
Archer is a Swedish-made self-propelled artillery system where the guns are actually mounted on trucks. The system moves quickly, fires rapidly and is very accurate.
"There is a lot at stake now. Ukraine is warning of massive Russian attacks. In this situation, military support is extremely important," Kristersson explained.
This is the tenth package of military aid from Sweden to Ukraine. The country has previously donated NLAW anti-tank weapons, which have already demonstrated their effectiveness on the battlefield.
