A Commanded shot is a small unit of musketeers temporarily attached to other units (usually horse) to provide firepower.
I come across historical reports of the battle of Rocroi saying French 'commanded shots' were "displayed between cavalry units". Two contemporary maps show the order of the battles of Rocroi (1643) and Les Avins (1635) where those commanded shots were put in the intervals of the only first row of cavalry (that is in checkerboard formation, like the infantry) at least at the start of the battle, in both wings :

Battle of Les Avins

Military historian John A. Lynn also wrote : "To bolster his cavalry, (French) Henri (IV) also interspersed companies of musketeers betwen his squadrons, a practice that continued throughout the Thirty years' War'.
The Swedish Army is said to have done it too.
This is an order of battle hard to achieve in game, because of :
- the limited number of Commanded shots in the French Army (and to a less extent in the Swedish one) in the Vanilla Skirmish mode during 1635-1648 : 1 up to a medium force size, 2 for a large one and 3 for a very large one.
- and the limited width of the deployment zone that prevents checkerboard formations for both cavalry and infantry. For example :

About the 'limited' number of Commanded Shot :
1) With a Small force sized Army, I guess one can easily have 4/5 cavalry units. So one can achieve a 'Formation 1' on one wing (see above) and let 1/2 cavalry unit(s) in the other wing (that could/should also have their Commanded shot).
2) With a medium force size Army, one can have say about 7-9 Cavalry units and could attempt a 'Formation 2' on one wing and let 2-4 on the other one (again they could/should have their Command shot) but, in fact, one can actually get only one Commanded shot unit (not 2).
3) With a large force size Army, one can get 12 cavalry units and theoretically make one Formation 2 on one wing and one Formation 3 on the other have but one gets only 2 Commanded shots (not 5).

Formation 1, 2, 3 (blue : commanded shots ; Red : Cavalry)
I guess the limited number of Commanded shots is a matter of balance between armies and cost of units and also reflects what real battles actually were. Looking forward to learning as much in terms of gameplay (a gameplay I really like!) as in terms of History
Cheers!
PS : sorry as I focused on the Swedish and French. I don't know the other armies well enough to know if they used that same order
