IV8888 Blasts into Freedom Weekend with Cannon vs. Humvee Window – Results

While IEDs were a huge threat and continue to still be a large one, the rate at which the United States recognized the problem and pressed into the “up-armored” kits is a logistical triumph. The common thin-skinned Humvee went from light all-terrain utility vehicles to turtles right-quick.

The hardest part of armoring a are two-fold: joins/seams and the windows. Where metals and ceramic can be arranged to easily avoid loss of coverage, windows are far more difficult. They have defined areas they have to be. Combined with the weight requirement of the windows for the clear materials, it is a technical challenge.

Fortunately for our entertainment, IV8888 is going to put the armor to the test – not against modern threats such as fragmentation. Nay Nay, they are going to throw over a pound of lead fueled by good ol’ black powder at the armored screen?

Would our Soldiers, Airmen, Seamen, and Marines survive the direct onslaught?

Nope. The passengers of the fully up-armored humvees would have had a bad day. Even worse, the armored glass caused the solid projectile to fragment mightily, which put some rather grevious wounds into the local watermelons.

Takeaway? Don’t charge an old cannon with an up-armored humvee. Assuming the cannon crew can actually aim it effectively, you may lose.

    Because what we needed was another video on how to defeat our own armored vehicles, using rudimentary technology that can be quickly and inexpensively fabricated into an IED concept. Terrorism TTP’s.

      37mm Parrott rifles aren’t really what I’d call rudimentary. If you can make that, you can make modern AT guns, which do the same thing to this sort of armor.

      • Jared Rizzo

        I mean the concept. I wouldn’t expect them to remake the cannon itself. Just knowing what can penetrate the windows more easily. A .50 BMG or Russian equivalent doesn’t. But this thing can. I’m no expert on artillery, but to my knowledge the rifling itself wouldn’t necessarily aid in penetrating the window. So that would lead me to believe that the weight, speed, and shape of the projectile are what lent to it penetrating. Those are things that can be more easily incorporated into an IED design. Honestly, I doubt it’s very a very sound plan to try targeting just the window. For me, the ‘interesting factor’ isn’t outweighed by the potential enemy’s use of this info. YMMV

          EFPs are the main threat, these days. This really is a non-issue.

          On the technical side, either 12.7mm NATO or the 12.7x108mm will hole-punch that window, given a couple of hits.

          On the rifled cannon technical side, the reason for the penetration is indeed related to being able to send the projectile reliably point-first. A round ball would have more of an issue, as would hitting base-first.

      I think you meant to say ‘time traveling’ TTPs.

    • John Deagan

      I’m pretty sure anyone with a few minutes of time for quiet contemplation could have come up with an equally ineffective concept.

    • Drew Coleman

      Because muzzle loading single shot black powder cannons are so very practical on a modern battlefield…

  • USMC03Vet

    And just think that is a half scale replica. Imagine those cannons on ships firing 32 lbs projectiles in a volley of hundreds. Ye olden times was serious business.

    • Sunshine_Shooter

      Brutal and short were the lives of men back then.

      • iksnilol

        And being a surgeon was super easy.

        Truly great times.

        • USMC03Vet

          I think it was the other way around. Lack of qualified doctors resulting in numerous amputations.

          • iksnilol

            Nah, it was just that people were so easily killed that being a surgeon was hella easy. Either you lop something off or you just euthanize the feller.

            Easy peasy, none of that pesky “actually doing your job” stuff that gets in the way nowadays.

    • CavScout

      A ship cannon (maybe half size, but still) is being put up against our dune buggy’s glass windshield at very close range…
      Not against our ships, our tanks, or even the armor on our dune buggy… but a windshield… That’s not making me rethink our tough or effective our modern stuff is compard to then…

  • Rodford Smith

    During the US Civil War it was not uncommon for Cavalry officers on both sides to wear steel armor vests. These were quite capable of resisting the small arms fire of the day, even the full-power military rifles and muskets. In a book I have on the history of armor there’s a photo of such a vest in a museum. It has several small dents… and one large hole. The caption explains that the wearer charged an artillery emplacement, and the crew got off a lucky shot.

    • mosinman

      that’s what i was guessing these small bore cannons were for

  • Sid Collins

    But the glass was not designed to meet that level of impact resistance. .50BMG? Yes. But firing an artillery piece at the glass is beyond the design requirement. Shrapnel, blast wave… yes. Firing even a small main gun like a Bradley or BMP weapon at an uparmored Humvee is a guaranteed kill.

  • Zebra Dun

    DANG! The Parrots back in those days must have been T-Rex sized!

  • Rocketman

    So now I guess that the bad guys in Iraq should go out and replace their AK-47’s with 1863 Springfields huh?
