I was just saying it all the time.
In regard of reasons, I think that such situations like cowardice or unfair approach was in minority. In most cases it was some sort of passive lazines, that means Frenchmen were not willing to work in wartime conditions. For example there was no will in having patrols since dawn, and tendency to have peace-like dinners with lots of wine. There were also many problems with organisation, both in getting equipment, and to arrange properly functioning observation posts. Simply, the system did not work, and the Frenchmen were not willing to introduce any changes. Lack of discipline is also mentioned. Sometimes this was combined with arrogance, but I would not say it was a general observation.
In regard of aircraft, a lot of criticism in case of GC I/145 flying Cyclones. There were some problems to get them working, and I recall a story, that a factory mechanic was unable to set those aircraft properly, having no documentation. Several pilots complained about low performance of MS-406s, and I know at least one pilot complained of the pneumatic firing system. On the other hand it seems few pilots loved D-520s.

Yes, this could have been a contributing factor to the situation in GC II/1.
It does not change the fact, Poles have seen that unit in a terrible condition, and that their description causes the concern.
