Squadrons formed by volunteers in Germany, not counting the Italian squadrons

In this image we have the [57th](https://en.wikipedia.org/wiki/33rd_Waffen_Grenadier_Division_of_the_SS_Charlemagne_(1st_French)) and [58th](https://en.wikipedia.org/wiki/33rd_Waffen_Grenadier_Division_of_the_SS_Charlemagne_(1st_French)) French Grenadier Regiments, which were part of the [33rd Waffen Grenadier Division of the SS "Charlemagne" (1st French)](https://en.wikipedia.org/wiki/33rd_Waffen_Grenadier_Division_of_the_SS_Charlemagne_(1st_French)). These regiments were formed by French volunteers serving in the Waffen-SS. It would be easy to implement because French voice lines already exist in the game.

We also have the [503rd Heavy Panzer Battalion](https://en.wikipedia.org/wiki/503rd_Heavy_Panzer_Battalion), a Wehrmacht armored unit that operated independently but was attached at times to divisions like the [11th Panzergrenadier Division](https://en.wikipedia.org/wiki/11th_Panzergrenadier_Division_(Wehrmacht)). Most of its personnel were German, but it also included Danish volunteers in its final stages.

There is also the [15th Fusilier Battalion](https://en.wikipedia.org/wiki/15th_Waffen_Grenadier_Division_of_the_SS_(1st_Latvian)#Fusilier_battalion) of the [15th Waffen Grenadier Division of the SS (1st Latvian)](https://en.wikipedia.org/wiki/15th_Waffen_Grenadier_Division_of_the_SS_(1st_Latvian)), composed mainly of Latvian volunteers fighting for the Waffen-SS.

Finally, the [11th Pioneer Battalion](https://en.wikipedia.org/wiki/11th_Pioneer_Battalion_(Wehrmacht)) belonged to the [11th Panzergrenadier Division](https://en.wikipedia.org/wiki/11th_Panzergrenadier_Division_(Wehrmacht)) of the Wehrmacht. It included volunteers from Germany, Norway, Denmark, Flanders (a Dutch-speaking region of Belgium), as well as some from Finland and the Netherlands.
