In response to some of the reviews posted here and in other episodes, that essentially pan the show for its lack of realism or authenticity, there really are limits to what a show like this can do. For instance, of course this episode arc wasn't shot in the Philippines, the very high costs for shooting on location would prohibit it. I think you'll find that the show is mostly shot in locations around Southern California, which provides a variety of sites and terrain that can be dressed up to look like any location they need. The "Gucci" hotel they're staying in for the mission is not in the Philippines, but appears to be the Hyatt Regency in Newport Beach. SoCal has a pretty large Filipino-American population, so it's likely that the extras on screen are locals from SoCal, who are 2nd, 3rd & 4th gen which might explain why the accents and dialect is off.
As for the lack of respect for military protocol, I didn't serve so I don't have as much insight, but this is the case in every military show and movie I've ever seen (Top Gun Maverick a recent example). It seems in order to have an edgy, heroic character like Jason (Bravo 1), that character has to have a disregard for command, and routinely violate orders to save the mission.
I guess I'm saying just enjoy the show and its make-believe reality ... find humor in how ridiculous the distortions and goofs are, and look forward to Season 6!
