I would be interested in what proportion of rifles were generally present in the following units in Spain/Portugal; the information in brackets indicates what I have found myself:
- a typical company of the 5/60th and 95th Regiments (all)
- a typical company of the 1st and 2nd KGL Light Battalions (initially 1-in-6, improving to 1-in-3)
- a typical light company of a KGL Line Battalion (1/2 or all of the sharpshooter platoon)
- the three "skirmish line" companies of the Brunswick Oels (all)
- a typical "atiradores" company of a Cacadores battalion (all)

During the American Revolution, it was usual for the light company of a British Line infantry battalion to have a number of men armed with rifles (ditto rifled carbines in most/all troops of a light cavalry regiment). Did this practice continue into the French Revolutionary and Napoleonic Wars, or were all the rifles concentrated in the units listed above?

Many thanks.
