Update on the Red October-incident

October 19, 2014

Welcome to the homepage of Robin Häggblom, better known as Corporal Frisk. I am an independent Finnish defence analyst, with experience of over a decade of sharing my opinions to anyone who wants to listen. My main areas of expertise are the naval and air domains, though I do dabble in other fields as well. In addition to here, you will also find me on Twitter and Bluesky, and do check out my articles and contributions on other sites in the links above the blog posts!
