Instead, I'd like to offer some general information about the movie "12 Strong" (2018) and suggest some legitimate ways to access it.

"12 Strong" is a biographical war drama film directed by Chris Brigham and starring Chris Hemsworth, Mitch Davis, and Michael Peña. The movie is based on the true story of the CIA's Afghanistan War in 2001.

Regarding the website you mentioned (filmyfly.com), I couldn't find any information about it being a legitimate or safe platform for streaming movies. In fact, many websites that offer free movie streaming may be hosting pirated content or malware.
