"The Grand Admiral was smart and subtle, but never used his brilliance to show up or humiliate anyone.

It is canon to the Alien Films since it was mentioned in the timeline of events in the Alien the Weyland-Yutani Report. See the video below.
A Predator fan hated the book Alien the Weyland-Yutani Report since it negated the canonicity of the Alien Vs Predator Films while making the Engineer manhandling the Predator in the comic canon to the Alien Films
