I applaud all the work done by the people who contribute to Kronoskaf. However, look at their "disclaimer" on the first page – "no guarantee of validity."
Using Krnoskaf, I just dug into the organization of Austrian Musketeer and Prussian Musketeer battalions (no numbers given for Prussian Fusilier, or Austrian Grenz units).
Essentially for the opening of the 7YW:
Aust: Austrian "book" strength of 2 nattalions of 18 officers and 798 men – 816 persons each battalion. Had 6 companies.
2 grenadier companies of 100 men each.
Pruss: 2 battalions of 856 persons, plus 2 grenadier companies. Battalions had 5 administrative companies that fought as 4 companies of equal size in battle.
Later stated that a 4 company grenadier battalion was supposed to have 754 men! Nearly double a 4-company composite Austrian grenadier battalion.
