Not very realistic. I just started the movie and off the bat, I already see some errors. Conventional US forces, even Green Berets don't use the H&K416 rifle. 1st SFOD-D and DEVGRU use that platform and some are phasing it out. Secondly there is no way in hell, US Forces in 2018 would be driving an open top Humvee, especially off base to a HVT target location, they'd be using MRAPs, JLTVs, or at least at a minimum uparmored Humvees.
In addition there's no way a two vehicle element would venture out to raid target, especially three hours out. These scenarios just don't make any real world sense. In addition the non convertible Humvee is not even uparmored, in 2018. These were issues in the early years, not in 2018.
The whole reason no competent CO would send out two vehicles and eight men to secure an IED factory three hours out, is so such a scenario wouldn't arise where they're ambushed and fighting ten against one. The writers of this movie conjured up the exact fubar events which would lead to the situation it led to, chaos.
When Kinley gave Ahmed the AK, he didn't give him any extra magazines, Ahmed is firing his weapon on full-auto in short bursts, did he get a cheat code where he doesn't have to reload? As for the US Forces, they're firing their carbines in full-auto, no US Soldier would do that unless he's on a SAW, plus a rifle is more accurate and effective in semi-auto.
Kinley asks Ahmed if his "gun is up," Ahmed racks his firearm, and says "it's up." In this situation when a loaded firearm's charging handle is reciprocated, it would eject a loaded bullet, and load a fresh one from the magazine. He said his gun was loaded but when he charged it, no bullet ejected. Like I said earlier, he's been on one magazine the whole firefight, and he's still good.
These are the errors I've found and I'm at the 42 minute mark. There's a bunch I didn't even address in the former write up. I just have a difficult time watching unrealistic movies.
I also noticed Kinley gives Ahmed a Beretta M9A3, the US Military never adopted the M9A3, they have the M9. Then during the Modular Handgun System competition the US Military selected the M17 and M18 made by Sig Sauer as the replacement for the M9.
Here's another cheat code moment, when Kinley goes off on his own to find Ahmed, the contractor gives him a a sat phone, $10k in cash, and he says "an M4 and six magazines." After Kinley hooks up with Ahmed and they get into contact, Ahmed is also armed with an M4. Where did Ahmed's M4 come from? Yes, the Taliban now have US weapons but came as a result of the 2021 withdrawal where the hajis raided weapons depots and collected abandoned weapons from the ANA. That's not to say that lost or stolen US weapons sold by corrupt ANA to the Taliban weren't around, but Ahmed was not Taliban, so for a friendly to be in possession of an M4 is so unlikely. He would more likely have an AK platform like the driver of the jingle truck who fought alongside Kinley and Ahmed on the dam.
