I would like to make a request for French translation of the words listed below. I am interested in terms which were in use in France in 1940.

- ground command centre (responsible for ground controlled interceptions),
- a small unit consisting of 3 airplanes (in German it is Kette)? patrouille?
- commander (e.g. flight commander, squadron commander)
- oxygen installation
- unit [military unit]
- subunit

Thanks in advance!
