  1. Dunno if that has been posted here before, but the YouTube algorithm has struck again. The APFSDS model wasn't specified, only that it is a 120mm sabot. The failure seen here apparently stems from a destruction of the fin assembly, which also resulted in tip detachment from the long rod's main section.
  2. Soldier from 1st ID peeking around a corner by leveraging the wireless connection between his ENVG-B and his LMG's sight (Family of Weapons Sights - Individual [FWS-I]). This feature even allows soldiers to more or less accurately shoot from the hip (not that it's encouraged, though).

  3. Combat as seen through L3 Harris' Enhanced Night Vision Goggles - Binoculars (ENVG-B), which is gradually replacing the AN/PVS-14. The unit here is 4th Battalion, 23rd Infantry Regiment, 2nd Stryker Brigade Combat Team, 7th Infantry Division, going through a live-fire exercise at Joint Base Lewis-McChord (WA), on April 19. View mode is "Outline Mode Fused + AR/RTA" (Augmented Reality/Rapid Target Acquisition). The ENVG-B reportedly allowed the wearers to engage targets twice farther away than with the PVS-14.
  4. Is Aermet also capable of this "heat reset"? IIRC it does not use intermetallic precipitation to attain high hardness, but carbide [(Mo,Cr)2C?] precipitation. 900°F-aged Aermet 100, in particular, has fracture and notch toughness exceeding that of maraging steel (I believe A100 was selected for the landing gear of the F/A-18E/F because the Navy was not satisfied with maraging steel), which makes me wonder if it was ever considered for inclusion into armor packages (even in small amounts) despite its very high price.
  5. Is friction stir welding a (technologically or economically, take your pick) viable way to mate maraging steel plates (let's say something like 18Ni2400) or does it require extensive side treatment to make sure the crystalline structure is not weakened in and around (HAZ) the weld due to the heat? I also seem to recall reading some time ago that there were concerns about the durability of FSW equipment when working with MS, but I don't know if they're still relevant nowadays.
  6. Chanced upon this on imgur: an SPG sound suppressor, at the Military Training Area in Meppen, Germany. Vehicle in question is a M109G. EDIT:
  7. Looks like a flipped-over FASTDRAW. That turret is guaranteed to have fat cheeks... The XM91 autoloader on the M1 CATTB had 17 rounds and those were 140mm, though that tank was supposed to have TWO extra carousels (22 rounds, folded) inside the hull for reloads:
  8. That's from the AUSA Global Force Symposium and Exposition from March 26-28 (scroll above on this page).
  9. ^--- ...I...I don't feel so good now. Is there no end to his Gavinitis?
  10. ^-- Also, the steel-encased part does not reveal whether they are talking about a fully-enclosed NERA package (with the steel possibly acting as shatter plate, unless they have DU front plates to fill that role) that's lowered into the armor cavities or if it merely refers to the cavity walls (the "outer skin" of the turret) being made of steel.
  11. Wasn't the HAP armor previously described as steel-encased NERA arrays with DU backplates or interstitial DU meshing? Can't remember which piece of literature mentioned it or somewhat alluded to it (maybe DOE, not certain).
  12. @Ramlaen: did you notice this? IMHO, it's a bit small to be the mystery cylinder on the M1A2C, but it's the right shape. A zoom on that part of the exhibit reveals it to be the Blackstone Vehicle Mount Kit (VMK). https://www.leonardodrs.com/media/6608/blackstone_vm_datasheet.pdf
  13. To illustrate Ramlaen's explanation: P.S. That is, of course, the old XM8, not the current, up-to-date M8. EDIT: didn't realize Ramlaen had already posted them on the first page, I thought I was just re-posting stuff he had only dropped in the AW forums (RIP, BTW).
  14. ??? Apparently, the M109A8 won't have an autoloader before 2024. Source I'm a bit confused about the first paragraph, since there are already a couple A8s rolling around...unless they are officially not type-classified as M109E8s but as mere version-agnostic testbeds.
  15. Given that it has a ring of circular apertures above the main optic, I suspect it's some sort of flash/laser beam detector. Maybe a soft-kill APS component to complement the hard-kill Iron Fist? It's either that or an anti-sniper system (though the latter, like the Raytheon Boomerang, would rely more on microphones, rather than optical sensors, for source triangulation).
  16. ^-- Except Ramlaen posted pictures attesting to this turret extension (distance from turret edge to ARAT-2 mount and the fact that the turret cheeks now nearly completely cover the gun mantlet's sides). No need for a tinfoil hat here.
  17. I'm usually skeptical due to angles of capture and possible turret (which also happens to be assymetrical, as it is thicker on the right side to accommodate the commander and gunner stations) traverse angle, but the mount for the foremost ARAT-2 ERA is indeed farther from the turret cheek's corner on the A2C than it is on the A2B. While it is not bode well for the Abrams' weight, it is nice to see its protection is still updated beyond merely swapping the contents of the armor cavities. As for the hull geometry, can't tell on my little screen.
  18. Just found this in my YouTube suggestions today - the changing of the tracks of a Sherman Firefly, by volunteers at the Belgian tank museum in Bastogne. Dunno if it has already been posted (text is in Flemish, by the way), but here you go: The uploader also has a fair share of tank/army videos.
  19. Still not known, alas. We suppose it's some sort of anti-IED jammer though I remember seeing pics of an AMPV with that cylinder and a CREW Duke v3, so nothing's certain (unless they cover different parts of the spectrum). It's also suspected it acts in concert with that black bar that's standing next to the driver's hatch. EDIT: yep, it was an AMPV, Mission Command variant. You can clearly see the Duke v3 antenna behind that cylinder. EDIT bis: The only thing I found so far, that remotely looks like that cylinder, is something called the Assured Positioning, Navigation and Timing (A-PNT) - Mounted / Anti-Jam Antenna System (AJAS): https://asc.army.mil/web/portfolio-item/a-pnt-mounted-ajas/ The antenna cover's texture is similar, but it's obviously squatter.
