A total of 429 Finns fought alongside many foreign volunteers of "Wiking" Division. They were scattered throughout the division, but about a half of them served in the infantry of SS-Regiment "Nordland".  

The most experienced of all Finnish volunteers in "Wiking" Division was SS-Hauptsturmführer (Captain) Y. P. I. Kaila, veteran of the Spanish Civil War and Finnish-Russo Winter War. He tells how "Wiking" attacked and his opinion on training in Waffen-SS: 
 

"We moved usually on to enemy contact in lorries and when the first machine guns began to fire us, we jumped off and started our attack. The most common style of advancing during a battle was so called 'Schützenreihe' in which distances between each man were about 30 m and between squads 100 m. Slowly artillery fire directed against such formation didn't cause serious losses and we usually didn't take cover unless the shots became too near. When we were closer to enemy we rushed on special 'Schützenkeil' formation which afforded us better possibilities to shoot."    Panzerstrasse IV and the goal ahead: Rostov.  "I recognized lots of bravery, but hardly any battle-skill. SS-officers were not interested in tactical questions! A battle and bading a battle were considered so simple, that no special military skill was needed for these. Great German heroism throws such 'prosaism' into the shade."  "My impression on the training of SS-troops is based on their result, acting on a battlefield and in a battle and off-battle. In this respect I got very infavourable view."  (Excerpts from the book "Suomalaisia suursodassa" by Jukka Tyrkkö.)

After the Finnish Volunteer Battalion arrived to the front in January 1942 most of the "men of the division" joined the battalion. 81 men was already killed in action and nearly 200 men returned to Finland because they hadn't good enough posts in the battalion or division. One of the returners was SS-Hauptsturmführer Kaila, who was the Finnish candidate for the commander of the Finnish Battalion.

After the disbandation of the Finnish Volunteer Battalion in the summer of 1943 only a few men returned to Germany and rejoined their old division or other SS-unit, most of them in 1944. Most of them never returned to Finland again.
