The Iron Man suit can be manufactured in mass easily. The Avengers initiative is to defend Earth from imminent global threats that are beyond the warfighting capability of conventional military forces.

It will definitely help to have thousands of "men in the advanced suit" to fight alien-like threats. Why don't we see such a military unit in the MCU?

    Yes, there wasn't an army in there. Just some villains trying to replicate suit

    Those films do explain why there isn't an Iron Man army, but I'll go ahead and write it up into a full answer.

    @ZaidSyedMMd you're forgetting the Iron Legion in Iron Man 3 and in Age of Ultron

    “The Iron Man suit can be manufactured in mass easily.” You may have missed the extensive parts of Iron Man 2 that demonstrate it actually can't be. Apr 15, 2019 at 14:46

1 Answer 1


The short answer is: accountability. After Obadiah Stane's betrayal during Iron Man 1, the only people Tony trusts with the Iron Man technology are his best friend James Rhodes and (as of Endgame) his wife Pepper Potts, because he does not want to risk it being used for the sort of atrocities the Ten Rings used his weapons for in Iron Man 1. This is also the reason he shuts down Stark Industries' weapons division.

This idea of accountability, or of others getting their hands on the Iron Man tech, comes up time and time again throughout the Iron Man trilogy:

  • At the climax of Iron Man 1, Obadiah Stane builds and pilots the Iron Monger suit based on Tony's original prototype. This drives home to Tony just how dangerous the Iron Man tech could be in the wrong hands:

    OBADIAH: Ironic, isn't it, Tony? You tried to rid the world of weapons; you gave it its best one yet. And now, I'm gonna kill you with it.

  • The Senate Committee scene in Iron Man 2 is the US government asking Tony to turn over the Iron Man suit, presumably so they can mass-produce them. Tony point-blank refuses, because he knows that's what they're planning to do and doesn't want to be held accountable for what the government might do with them. It also demonstrates that the Iron Man suit isn't as easy to mass-produce as you believe: look at how Iran and North Korea's attempts went. (And just to justify Tony's paranoia even more, Captain America: The Winter Soldier reveals that the head of the committee, Senator Stern, worked for HYDRA.)

  • Then, later in Iron Man 2, the US military do get their hands on the Iron Man tech when James Rhodes brings them the Mk.II suit. Justin Hammer gets the contract to develop the mass-produced suits, and gets Ivan Vanko/Whiplash to assist him. This, of course, ends with Vanko hijacking the suits (including the one Rhodes is inside) and sending them on a violent rampage as part of his campaign to destroy Tony's legacy. This would only reinforce Tony's refusal to militarise the Iron Man program - what if those suits got hacked?

  • Interestingly, in Iron Man 3, there actually sort of is an Iron Man army - Tony has built dozens of suits that can all be remotely operated by JARVIS. However, if I recall correctly, he didn't build them specifically to serve as an army in case of a serious threat, but as a coping mechanism after the events of The Avengers left him with PTSD. At the end of the film, after coming to terms with his trauma and vowing to prioritise his relationship with Pepper over his Iron Man career, Tony destroys the surviving suits.

  • In Spider-Man: Far From Home, the villains use technology descended from various Stark Industries projects, and also acquire EDITH, a powerful AI/augmented reality system developed by Tony, midway through the film. It's nothing to do with the Iron Man tech, but like Iron Man 1, it demonstrates what can happen when Tony's inventions fall into the wrong hands.

It's been pointed out repeatedly in the comments that in Age of Ultron, Tony has another fleet of autonomous Iron Man suits, the Iron Legion. However, he uses them for crowd control to keep civilians safe while the Avengers do the actual battling. Presumably, he still doesn't trust others with the suits, and after Ultron hijacks the Iron Legion partway through the movie, I'm guessing he no longer trusts AIs with the suits either, hence why he hasn't rebuilt the Iron Legion since then. There's another autonomous suit in Spider-Man: Homecoming, but I believe Tony remote-controlled it directly rather than having an AI control it.

    It might be worth adding how Age of Ultron figures into this, though, because there he actually does plan and develop a sentient robot army for defending earth, precisely under the thoughts that it would help against all the threats from outer space.

    It's Ultron itself that decides to build a sentient robot army, maybe based on the footage of Tony's previous missions it sees in the database. What Tony Stark intended Ultron to be apart than "an A.I." is never stated.

    @Zachiel At the start of "Age of Ultron", we see the "Iron Legion", which are mass-produced autonomous Iron Man suits that Tony is using for crowd control. Ultron then co-opts the Iron Legion production facilities to create his own army. So, he has started building the robot army before the film begins. Apr 15, 2019 at 9:25

    They did try, and that was what the entire Hearing scene in Iron Man 2 was about. Specifically the government trying to co-opt the technology, and the argument (which seemed to have carried) was that the suit was part of Tony. Sep 11, 2019 at 14:38

    The Spider-Man suit from Infinity War probably also counts as Iron Man tech so there's a 3rd person he trusts with it Sep 12, 2019 at 11:13
