So...

Angels of Death includes several new formations, but of note are two new ones (okay maybe not "new" but "new to this book and now available to all chapters") with interesting names:

Stormlance Battle Demi-Company and Pinion Battle Demi-Company

The question I have is this: can you combine these with either themselves and/or a regular Battle Demi-Company under a Gladius Strike Force to form a full Battle Company?

Arguments both ways:

1. It doesn't say you can
2. It doesn't say you can't

Now, I'm of the OPINION that you should be able to, because otherwise, why name them XXX Battle Demi-Company? That's a poor argument, however, in terms of rules-lawyering, so I submit it to the group for discussion.
