From Lexicanum

A Waaagh! Banner is a huge standard carried by an Ork Warboss or someone in his squad (see: Banna Wava). They are decorated with glyphs which are used to show the warband's invincibility in battle as well as proclaim how nasty they are. There is also a religious aspect as it has been noted that Orks fight much more ferociously while in its presence.

The Waaagh! Banner in Dawn of War

The Waaagh! Banner is a light structure designed primarily as a base defence and population structure. It mounts a single weapon which can be upgraded several times while also boosting the numbers of Orks the tribe can support at any one time. The more of these the tribe has, the greater the number of warriors.
