[FH]Attach and Detach - how far does it go

Some people, and I'm one of them, create tables of organisation and
equipment for their units, I also often create them for the next two
levels up (at least in outline) but recently I have been wondering if
this is a pointless exercise and all I should be doing is having some
sort of idea what proportion of a particular troop type a force deploys.

One reason for this is I have been reading about the battle of Meggido
(yes I know it's WW1 but bear with me). One thing that struck me was the
amount of occasions where formations had sub-units attached or detached.
Here are some examples:

Detachments:

A cavalry division - nominally of 3 brigades, having 1 complete brigade
detached to another division and a second brigade having all three of
it's regiments detached (1 to guard Corp HQ, 1 to Guard the divisional
transport and 1 to Guard the divisional transport of another division)
leaving the Division with 1 Brigade, the Brigade HQ of a second and the
Divisional units.

A Cavalry Brigade - nominally of three regiments but with one regiment
detached to POW handling duties.

A Mounted Brigade - nominally of three regiments but with one regiment
detached completely and the other with 2 of its four squadrons detached.

Attachments:

An infantry division - with a cavalry brigade attached giving it 3
infantry brigades and a Cavalry brigade.

A mounted division - with an infantry brigade and 4 independent infantry
battalions attached.

So the question is how low does this kind of thing get now? and how low
will it get in the future. I know that platoons and companies get
shuffled around now to make task forces and battlegroups, but I'm not
sure if it makes any sense to go lower (attaching an individual MBT to
an infantry platoon).
