...Estonia currently operates 24 NATO standard FH-70 towed howitzers. Apart from the howitzers, Tallinn will send thousands of 155-mm artillery shells and hundreds of Karl-Gustaf anti-tank grenade launchers.

Estonia's defense minister Hanno Pevkur assured its people that the decision to send its 24 FH-70s to Ukraine would not affect the country's national defense because Tallinn is transitioning to K9 self-propelled howitzers produced by South Korea. The Estonian Ministry of Defense signed a contract last year for 12 K9 artillery systems.

"They've been very successful in Ukraine, so the Ukrainians will be delighted, I am sure, to get another 12. I think that brings that total to over 40 now, closing on 50 Caesars in Ukraine. And the fact that the French are stepping up their training of Ukrainian troops will be welcome too. It's not just the French who are doing it; the British are contributing even more, I think, to the training [?!] than the French are."
