As you know, I'm not a member of the Team, but if you had this picture in mind:
I can definitely say it's a kettle hat, both the one on the soldier on your right-hand side, and the one on the soldier on your left-hand side.. Aside from Spaniards, the English, the Germans, the Swedes, the Italians... also used morion helmets, but it was put in use in XVI century, and Tsardoms pretty much... ends then.
If the pointy tip on the top of the leftmost helmet is what got you thinking there's a morion on this picture, then check out this XV century kettle hat:
If the slope on the rightmost helmet's brim is the reason - well, the morion is normally taller and it's supposed to have a crest or a tip on the top. Kettle hat again.
Cheers.
