How Does S O E F Section Fit Into the French Resistance?

i spoke to rob lyman about this when he did his book about the amion and prison brake in operation jericho. He says s o e f section is just a bit rubbish, i meand it's because they're british people going into placesthe reason our f section works better is because they're french who are making most of existing networks that they already know. Whereas some one like francis suttle, he might speak fluent french and might be a massive francpal, but he doesn't have that inbuilt network already there.
