Dr. Peter Hambro Mikkelsen, Department for Environmental Archaeology and Conservation Moesgård Museum, Denmark:

"For several years, Roland Warzecha has been cooperating with Moesgaard Museum and the Archaeological Department at Aarhus University in exploring Viking Age weapons use and combat techniques. The actual combat seems to have been much more sophisticated than is usually envisioned by the community of archaeologists. Roland has great communicative skills which facilitates understanding the complexities of real fighting with sword and shield."
