DINA manpower composition in 1940

[Kelvin]

Hello, French DINA light and heavy artillery regiment did have 872 and 647 colonial recruits, I only know 5e DINA they had Colonial Sengalese Mixed artillery regiment in both light and heavy regiments and 7e DINA had French artillery regiment but I would like to ask how about 1er, 2e, 3e, 4e and 6e DINA artillery regiments (light and heavy), how their colonial recruits composition ? are they all same national in one artillery regiment or mixture of Tunisian, Algerian and Moroccan ?

Also how about other units in sapper companies, radio company, telegraph company, GSD and GQD, anyone can help on that ? Thank
