Special Operations Executive - Spying, human intelligence, sending teams behind enemy lines to train guerrillas or partisans and lead them in operations.

Military Intelligence sections - I am sure you heard of MI5, MI6? James Bond? Set up during WW1. They had about twenty of them during WW2, MI1 - MI19, most as subsections charged with different countries or theaters. Most are defunct now, MI5 has become the Secret Service and MI6 has become the Secret Intelligence Service.

The SAS primarily was tasked with raids behind enemy lines and then returning to friendly lines. They would secondarily maintain operations from a secret base behind enemy lines and if there was an opportunity to, recruit, train and lead guerrillas.

The SOE had teams that were set up to do just that, they would drop behind the lines carrying weapons and supplies for full strength platoons, at least forty men on the books. They would be roughly three men, a British commissioned officer in charge, a British non commissioned radio operator, brought in from armored units for their perceived broad range of fighting skills, coupled with their knowledge of radios and experience working with small close–knit teams, and a guide, usually an officer of the native countries intelligence service. They didn't always drop with the guide and sometimes could have some extra people.

As for MI sections, in the game, Elizabeth Salter, she is an MI5 agent. That should give you an idea, human intelligence, etcetera.
