I ran into a video about how they trained lady soviet spys. they seemed to have went to great lengths. The male counterpart was called romeos. I guess they were actually trained in seduction. To me the male counterpart was most likely different to the winter soldier program but who knows. also if there is a real black widow it might even involve the use underground bases, extreme mk ultra, and even some kind of super soldier serum or implants to modify them. so in other words the video might just be backround info about how the soviets did things.  the link. https://youtu.be/LJPhtKyBDNQ?si=KRQ6jmG-yv8ea0io
