They are, those Knights are the Teutonic Knights.
A German order that not only fought in the Crusades of the Middle east,
But also in North Eastern Europe against the Lithuanians. (Pretty sure the Lithuanians...)
Yes, against the pagans in the area of what is today Lithuania, Latvia and Estonia.
Some of the Teutonic orders of Crusaders were known as Livonians.
In 1202 Bishop Albert of Livonia founded the Brotherhood of the Sword, an Order like the Teutonic Knights. In 1236 the remnants merged with the Teutonic Knights, and were known as the Livonian Order.
Here are some pictures from cover art of Zvezda toy soldiers (25mm) that are made in Russia (Italeri also has a license to release some of them in the West, so you may be familiar with them at hobby shops). The first is 'Crusaders', the second is Teutonic Knights, the third is Livonian and the fourth is Teutonic again.
