At the start of the episode, you can see a C-130 aircraft flying as if Alpha team is en route somewhere. When the camera shows the interior of the aircraft with the team in it, it is a lot smaller than an actual C-130 cargo bay.
The reason the team uses AK-47s is so the mission cannot be tied to the US. This is undone when Gerhardt executes Pari with a .45 pistol. The US is the only major nation that uses .45 caliber pistols. To obscure who was there, a 9mm would have been a better choice, as that is the pistol choice of a great many nations.
The credits list the character played by Conor O'Farrell as "Major General Heath". However, the uniform he is wearing displays three stars on his shoulders. This is the rank of an army Lieutenant General, not a Major General.
The team is shown with suppressed AK-47s. The suppressors are sized for pistols, and are a) too small to effectively suppress rifle rounds, and b) would likely explode from the increased pressure.
