If you have a lot of objects in your scene you can speed up rendering a
lot with efficient grouping, for example when when you have a regular
tiling and unionize the items in a tree structure you will get optimal
performance, because through the automatic bounding Povray will not need
to test every ray against every single object.

What did you have in mind? I'm no phalanx expert, so... you mean like a
guy on a horse in front of the phalanx holding a flag? But I haven't
modelled a horse, so...

Not necessarily. On most battlefields - until the WW's. Now they
probably use GPS-brain implants - armies had a guy walking or riding a
horse with the troups holding up a flag (or standard) so the soldiers
knew where to go.
For an equestrian example, check:

For a "pedestrian" version, check:

Okay, that's not that bad :-)
Let's just say, if I ever want to use focal blur, I think I can do it on my
dad's P3-800...hehe. Use your parents wisely ;-)

Now there is a job that would have to pay well! I presume that this would be
equally useful for the opposing soldiers, a sort of "shoot here" sign.

I'm not sure, but i usually get quite a lot of speed increase this way.
Probably the difference is not that large with such a fairly simple
scene.

Indeed. It was a very good military strategy to aim at the standard
bearers first to confuse their troops. Just like in todays combats,
factions will try to first take down coms centers.
