Mountain Eagle never intended to force their way into Bolonicov's factory...
Because they were only six people, storming in with such a disadvantage in numbers would not be suicidal for sure, but it would definitely be an inefficient choice.
From the beginning, Mountain Eagle had seen the factory as bait in a surrounding strategy, even going so far as to release information through Iron Cavalry Company that he was Snowden's bodyguard, all to draw more enemies to them.
He planned to thoroughly stir chaos in the area, using the confusion to exhaust all the enemies as much as possible...
As long as enough teams and organizations are crippled, soon everyone will know that Bolonicov suffered a hit for helping an American enter Moscow...
Everyone will know that Snowden has a team of extremely formidable bodyguards; they may not always be by Snowden's side, but anyone with ill intent towards him is their target.
