Why is "Research and Development Branch" trending?

Wikipedia Overview

In the United States, the Research and Development Branch was a branch of the Office of Strategic Services (OSS), whose mission was to research and develop new technologies to aide Allied missions against the Axis powers during World War II. Operating in conjunction with the National Defense Research Committee to fulfill the special requests by OSS Headquarters, R&D was responsible for designing, testing, and procuring specialized equipment to support covert and clandestine operations, improve intelligence collection, and enable sabotage activities. R&D adapted and refined many clandestine issue items and supplied equipment primarily to the Secret Intelligence (SI) and Special Operations (SO) branches of OSS. The inventions of R&D were originated both by members of the US government, and by average US citizens who would submit their ideas – by the thousands – to the National Inventors Council. Most of these publicly originated ideas were nonsensical, and R&D would occasionally be forced to entertain them, especially if they were generated by high-ranking government officials, such as the infamous Bat bomb and Cat bomb experiments.
