On the OMFV

We’ve had some recent news on the OMFV program, with Rheinmetall being disqualified for not showing up for the Engineering & Manufacturing Design (EMD) phase, so let’s dig in.

First, let’s laugh a bit at the “competition” now with a single entrant. Even though, technically, someone else could enter a bid in 2023. If the program stays around that long. Those competitors wouldn’t get US Army funding and feedback from the EMD portion of the program, so they’d be at a significant financial disadvantage.

Okay, now that we’ve gotten our snark out of the way, let’s get serious. Yet again, we’re trying to replace the Bradley. What are the problems with the Bradley? So far, I’ve found the following three commonly cited (in no particular order):

1) Insufficient protection against current and near future threats, even with existing up-armor kits installed.
2) Insufficient power capacity for all current systems, let alone future upgrades.
3) Insufficient dismount capacity.

That said, OMFV only seems to worry about (1) and (2), since it does not require entrants to carry a full, nine-man dismount squad. And the one entrant from General Dynamics (which I believe is called Griffin IV), has capacity for the minimum required dismounts only. I think we’re still waiting on the DTIC or RAND corp. study on “Why Six Dismounts is Sufficient”, after they so kindly wrote a bit on why it’s so important for the GCV to carry nine dismounts.1

Anyway, the current requirements are tough enough. The following three are probably going to be extremely tough to meet:

  • Entrants must provide excellent protection (details are sparse, but presumably superior to that of the Bradley)
  • Entrants must have a 20% growth capacity
  • Two (2) entrants must be transportable in a C-17

I’m not entirely sure that this is doable. BAE didn’t think so, which is why they didn’t bother to enter anything into this phase. But GDLS seems to think they can do it.

I would have liked to have seen the Puma entered into the EMD to compete with the Griffin, but since its made by a collaboration between Rheinmetall and KMW, there’s little reason for Rheinmetall to enter it when they had their (now disqualified) KF41.

Of course, Puma was a GCV alternative that the GAO looked at, and was recommended over developing the higher-risk GCV prototype vehicles, despite holding fewer dismounts. Two can fit in a C-17 in the stripped-down configuration that is used to get it into an A400m. And the protection is pretty fantastic.

Obvious problems include that it’s very expensive, I have no idea how much growth capacity is in the design right now, the turret would have to be redone to carry the US-Army preferred 50mm XM913 autocannon, it’s expensive, there’s no provision at present for a hard-kill active protection system, the coax gun is still 5.56mm, the MELLS ATGM launcher isn’t done and did I mention it’s expensive? At a minimum, competitors are required to demonstrate an upgrade path to the 50mm gun. Oh, and the US Army would have to be okay with having to transport and install the rest of the armor before they used their air-transported Pumas.

As it is, we’ll see how the program goes. I’m not going to hold my breath.

  1. Something along the lines of, it was closer than the dark-matter-free paper authors thought, so it wasn’t strange at all. 

Open Gear Retrospective: Year One

I’ve been having a blast in Open, and thought I’d take a bit to talk through some of my gear and the small changes I’ve made. My gun has been running great, and I’m super happy about that. Let’s look at some of the other stuff, and one gun part swap.

1) Holster: Double Alpha Alpha-X vs. Everglades Magnetic Race Holster
I started with a purchase of a ‘belt kit’ from Double Alpha, which included their Alpha-X race holster. This holster requires inserts to fit the trigger guard of your firearm. Since I’m using the relatively new Lone Star Innovations Outlaw grip on my race gun, which doesn’t have an insert explicitly made for it, I guessed and got the insert for the Phoenix Trinity Evo grip.

Was this module the right choice?
Yes. Or, at least, it was retained correctly and drew (mostly) fine.

Why did I switch?
Sometimes I found that I could get my gun to snag a little on the draw. I also wanted something with a bit more positioning change options, so I gave the Everglades Magnetic Race Holster (MRH) a try.

Is the MRH better?
Yes. Much smoother draw, nicer adjustment range for holster position, and the adjustments actually stay in place without a bunch of loctite. It also has a much bigger lever for the lock to keep the gun retained when moving, which is easier to sweep off on the draw. The only downside to the MRH is that its only for hi-cap 1911 platforms.

Which should you buy?
If you’re shooting a hi-cap 1911/2011 type platform, get the MRH. It’s just better.

2) Mag Pouches: Double Alpha Racemaster vs. Alpha-X
I opted to go for the Racemaster mag pouches in my belt kit.

Why did I switch?
I decided to give the Alpha-X a try since forum reviews indicated they had a superior mounting system design and I found that my mags could drag a little when drawing from the aluminum-bodied Racemasters. The Alpha-X pouches have plastic liners to try to correct this.

Which is better?
The Alpha-Xs are better. The belt attachment is a lot more secure, and only requires you to tweak/torque/loctite one screw instead of two. The plastic liner really does allow you to get a clean, slick mag draw even after you’ve messed around with tension. Plus, if you like to run your pouches bullets-out like me, the Alpha-Xs are way easier to set up that way. I’ll slowly switch out the Racemasters for Alpha-Xs, but being an open shooter, extra mag pouches are a seldom-used item anyway.

3) Magwell: Dawson ICE vs. Limcat V2
My awesome open gun came with a nice, big Dawson ICE magwell on it. This is a pretty typical choice and it’s been around for a while. It’s got an aluminum top with a replaceable plastic liner, so when you gouge it up after practicing reloads, you can just replace the liner rather than the whole magwell.

Why did I switch?
I noticed sometimes during reload practice that there was a way I could actually get my mag stuck in the grip if I didn’t rotate it correctly to align it with the grip. Some googling showed me that I wasn’t the only one with this problem, and Limcat made a magwell to try to fix it. The Limcat V2 magwell has an aluminum top and a hardened steel liner, which isn’t easily replaceable, but it should be resistant to getting all gouged up by reloads as you try to get faster.

Which is better?
The Limcat by far, even if I had to spend some time fitting it with a file. It’s got a shape that helps push your hand up higher on the grip, and the magwell’s narrower mouth and convex shape really does mean that you can’t get the mag to jam up. If you don’t miss the magwell, your reload is gonna happen. It’s a fantastic magwell design, which is probably why everyone is trying to copy it. And the hardened steel liner is, in fact, resistant to gouges.

4) Which helped more, minor kit tweaks or consistent practice?
Consistent Practice. Duh.

5) Do I want to try any other minor changes?
Of course. In no particular order, I’m considering trying the following:

  • Some kind of thumb rest, mostly because this is open and I can have one.
  • The Atlas ‘Ape Hanger’ racker, because it looks cool and it won’t smash your thumb if you flag it (old habits die hard).
  • The Limcat Heavy Brass V2 magwell, because I kinda like my current heavy gun, so why not try more weight low in it?
  • Possibly the SIG Romeo 3XL red dot, but that’s a lot more expensive than everything else on that list, so I might wait.

But really, the big thing is just get more practice.

DISCLAIMER: I paid my own money for all of the above parts and received $0.00 in compensation from any of the manufacturers listed here.

  1. Let’s see. Raimi’s trilogy is good, great, meh, and gets sad-sack Peter Parker right but doesn’t give him much time to be wisecracking Spider-Man. The Andrew Garfield movies are meh, I-didn’t-see-it, and make Peter Parker too cool. Spider-Verse is one of the best comic book movies of any kind ever. I didn’t see Venom. That’s maybe half good? Two-thirds? Anyway, the two MCU Spidey movies have been superb and great, respectively, because a) Tom Holland’s Peter Parker is still a dorky kid, and b) Tom Holland’s Spider-Man is properly confident. Some complaints about how Far From Home took him too far from home aside, Marvel Studios has a better record so far.

LAND 400 Downselect

Australia has announced the downselect results for the LAND 400 IFV competition. They chose Rheinmetall’s KF41 Lynx and Hanwha’s AS21 Redback to proceed to the next phase of competition. This means of course that the General Dynamics ASCOD 2/Ajax derivative and BAE’s CV90 are out.

This means that the two proposals derived from vehicles that are in service somewhere are out. While the LAND 400 requirements wanted something relatively ‘low risk’ it seems that new designs that share components with in service vehicles suffices. It also helps that the Lynx and the Redback were both designed with what the Australian army actually wanted in mind. Funny how that works. I’m glad they prioritized capabilities.

I’m not surprised the CV90 didn’t make the cut, since that’s an older design and it wasn’t very cutting edge when new. The ASCOD 2/Ajax proposal rejection was a little more surprising, as the Australians tend to have a lot of commonality with the UK. Anyway, it should be good to see how the two newer designs shake out.

Other Science and Technology Stories

  • Are insect populations actually declining? – A followup to a previously-shared story. In Puerto Rico, the answer appears to be ‘no, and if they were, it wouldn’t be because of temperature change, because there hasn’t actually been any’.
  • Bad ideas in computing: PingFS – It stores your files in the contents of ping packets to a remote server of your choice. It doesn’t work on LANs because the latency is too low.
  • Aluminum hydride, known primarily as a rocket fuel additive, makes a superb fuel cell fuel – At the top end, the aluminum hydride fuel cell system has better energy density than JP8 and a power unit, both by mass and volume. Being a solid powder, it also doesn’t take any compressive storage. Also, it contains 148 grams of hydrogen per liter of volume, twice the density of liquid hydrogen, to say nothing of compressed hydrogen gas. The only obstacle to widespread adoption is scale of production. A Bay Area company called Ardica Technologies is working on that, but they’re at kilogram-scale right now, and DoD is putting out feelers for more than 40,000 metric tons per year3.

Global Politics

  • One mechanism by which the Chinese economy might collapse – “It is needed to build more steel mills so as to build more shipyards, ports, railways and bridges so that more ships can be built to carry more iron ore to more ports and thence along more rails and bridges to more steel mills so as to build more shipyards, ports, railways …”
  • UK Parliament denies Boris Johnson’s second bid for an election – How it sounds to an outsider: “The Brexit fight is absolutely crucial to Britain’s survival as a democracy, which is why we mustn’t under any circumstances permit the people to weigh in.” I’m nearing the end of Massey’s Dreadnought, which covers a tumultuous time in British history during which political figures used snap election after snap election as referenda on the issues of the moment. Apparently that changed not merely this century, but also this decade.

Parvusimperator Reviews: Resident Evil 2 (Remake)

Remaking movies is a terrible, terrible idea. Remaking video games can be a great idea, and Resident Evil 2 is a good example of a remake done right. The original was made in 1998 on the original playstation, featuring PSX graphics, fixed perspective cameras, and the sort of “tank controls”1 that only die hard purists and masochists enjoy.

Modernizing the game was done with the help of the engine from Resident Evil 7, giving modern controls and excellent modern graphics. Interestingly, and unlike Resident Evil 7, the remake of Resident Evil 2 has a third-person perspective. It’s a well done third person, and I’m ok with that.

Some of the structure of Resident Evil 2 remains intact. You can choose between one of two characters, Leon Kennedy and Claire Redfield for your playthrough of the story, and then you can opt to play as the other character for a complimentary story. Leon and Claire have some different boss fights, different weapons, different collectibles, go through different areas, and even work with different NPC helpers. There’s plenty of replay value to be had here.

There’s more fun to be had in the extra modes. There’s The 4th Survivor, which changes the formula by giving you an inventory full of weapons and healing items, but has nothing for you to pick up to restock with. Then there are some DLC scenarios which add some new zombie types, lootable backpacks, explosive backpacks, and vending machines. The vending machines are a neat twist, with each one featuring three items, but you can only pick one of them.

If you’re a fan of survival horror, you owe it to yourself to pick this one up.


  1. Amusingly, while I love tanks almost as much as the Stavka, I do not enjoy classic Resident Evil “tank controls” at all.
