Agree . . . the abstract is of interest.
Makes me think and or reflect upon posturing in warfare . . . appearing taller (with plumed helmets), or more fierce with "paint" and similar decorations.
Mr. Barker spoke of berserkers in DBA or DBM, I believe.
Some rule sets allow them, some do not, as is their right.
To The Strongest! represents these as heroes as opposed to the "formed" units in other sets.
I am sure I read about them in that Vikings book reviewed recently . . .
