HKW found the 1808 regs for the Austrian Grenzer
it is essentially a cut down version version of the 1807 Exercier Reglent with most of the Linear drills cut out, but with a focus on columns. There are some interesting comments on skirmishing from p.112, but the bulk of that section is general principles rather than tactical details. It assumes the Grenzers already know quite a lot, as there is little about training unlike in the 1807 reg.
Austria was always short of money, so there were few training camps - in contrast to the two- year Camp of Boulogne. However, there is a description of a camp in Germany in autumn 1797, which adds some useful tactical details

Thanks - very interesting, Hussars in three ranks, and then as for infantry out of this third rank tactical reserves are formed.
Those carefully orchestrated manoeuvres were not that rare, I believe quite common, also in the Prussian Army.
The drill regulation about the Grenzer is quite interesting showing not only by the introduction of Carl that the Austrians clearly had the view that their main role was light infantry duties.
The famous Camp of Boulogne was not one training camp, but six (of which Boulogne was only one), centered on the following locations: Brest, Montreuil, Boulogne, St Omer, Bruges and Utrecht.
The troops assigned to each camp were orignally known by the name of their camps, such as the Camp of Bruges, etc. and were later designated as corps. For example, Lannes commanded 'the corps of the advance guard', Ney commanded the 'corps of the left', Davout commanded the 'corps of the right', and Soult commanded the 'corps of the center.' In 1805 the corps received numerical designations.
The overall designation of the troops on the Channel were designated the Armee des Cotes de l'Ocean in June 1803. The training was intense and continuous emphasis being placed on swift maneuver and individual marksmanship as well as infantry/artillery cooperation. The training was more than two years; in actuality it was closer to three.
In August 1805 the Armee des Cotes de l'Ocean became the Grande Armee.
The makeup of the newly-christened Grande Armee was interesting. They were not all veterans. One-third of the troops, including almost all of the officers and NCOs, were veterans with at least six years service. About half of the cavalry and forty-three percent of the infantry had seen some combat. Maybe one in thirty was a veteran of the old Royal Army. More were veterans from the volunteers of 1792-1794; the largest group were the conscripts called up in 1799-1800, but the remainder were new soldiers. All of them became highly trained together as comrades and became the best army in Europe.
Instead of Elting I recommend to read Alombert & Colin - the first volume of his La Campagne en Allemagne, this work discusses the Camps de Boulogne, perfectly adequate to say so (in fact Nabulieone signed his orders very often with Camp de Boulogne and the rest of the world did well know that he did address all camps) more competent then the Elting blurb cited above - I would appreciate when citing a work to use quotation marks.
