>>14739712You have three valkyries, carrying 10-12 guardsmen each? They all fly around separately, drop the guardsmen off at different places, fire at different targets. Each is a unit, each takes up one force-organization slot.
Now you need more valkyries to carry more guys? your force org is already full. Because guard are all about number you can still take more fliers, but they join the existing valkyrie units and have to move alongside them, shoot with them at the same target etc. You still only have 3 units.
This can be a problem. If you were doing the same thing with chimeras that aren't part of the force-org you wouldn't be limited to only three units, each chimera could be his own unit and move separately, fire at different targets etc.
