Fun weird thing I noticed - NATO with the Anglo countries all using Standard end up using 155mm guns. The Soviet Union, despite using metric ended up with 152mm (6 inch guns) artillery. China... seems to have a bit of everything, although it looks like they finally settled on 105mm/125mm for AFVs and 122mm/155mm for artillery
105s may not do modern armor at its best, but they still go through the sides of a tank just fine. You can only armor things so far before you degrade performance too much; even the Maus had thin areas in its armor plate and it was slower than a dead cow sliding up a hill. As it is, Centurion is hedging its bets but it's speed limit also comes from its suspension - it may be able to accelerate nicely with those new Continental engines, but it's not gonna win a race.
Also interesting that the west didn't really invest in rocket artillery during the Cold War until the M270 showed up. There really aren't equivalents for area-saturation like a Grad battalion lobbing a full salvo on an area.
Has anyone ever gotten use out of IFV firing ports? Generally once in contact, infantry should be outside where they can find cover instead of being conveniently grouped up so that one good RPG hit takes out the whole bunch. On the other hand, with a roof hatch, maybe you can rig up a way to fire an ATGM out of there, like the 120mm mortar carriers do.
The firing ports thing, you get a little use out of it but I don't know how much. Supposedly they're there to be used to let the infantry shoot at things while maintaining NBC protection, though I've wondered just what kind of connection allows that to work.
Roof hatch it has, and the Israelis (I keep coming back here but it's such a great here) rigged up 81mm and 120mm mortars in the back end of a Bimp firing through the roof hatch. I suppose it wouldn't be hard to put TOWs onboard as well and a launcher for them, just like the Jaguar 2.
1) I don't think Mirage IIIs are 'Hi' any more after a decade and a half with their period radars. F1s would be more 'hi' at that point, although I suppose you could swap avionics. Mirage 5s definitely don't count since they don't have all-weather capability in any role
Mirages still do well, and keeping the avionics upgraded would be a major point as the technology miniaturized. I don't know if you can cram a Cyrano IV radar where a Cyrano II goes, but I'd sure as heck try. It's still going to be a better radar than the MiG's, and the F-5A models lack radar entirely, so they had that going for them. Mirage IIIE also makes for fighterbomber capability, while the F-5 or MiG-21 would be pure air-superiority.
2) I'm pretty sure Mig-21s don't have much rough field capability and with their high wing-loading and lack of extra lift devices, also have a long take off roll. Those were two of the key points the Mig-23 was supposed to (and did) address with VG. If you look at a MiG-23 on the ground, you'll see just how massive its main landing gear are and also the high nose gear to give it a bit more AoA
According to Wikipedia, so throw a bucket of salt over one shoulder, it's capable of rough field takeoff and landing and it's pretty short. 830m takeoff distance, and 550m landing distance with a chute, plus they list takeoff weights for rough/planking versus paved. I'm going by those, but if it's exaggerated or not that capable then I'll go back to F-5s. Those I KNOW can take off and land on grass strips because I've seen film of them doing it, LOL. (It's in the Aviation Pictures thread if anyone wants to see)
Either way I need a light fighter of at least some moderate usefulness; I like the mixing of tech but I can go either way. And now I'm picturing MiG-21s refitted with Mavericks...
3) The F-5E is a fine plane. Mirages and F-5s... very Swiss. Also the Swiss Pz68 looks funny with its disproportionately sized domed turret.
It looks like a T-55 that got a nasty bee sting. The poor thing's so swollen, it's got to hurt...

4) Completely unrelated, the Japanese Type 60 recoilless rifle carrier never stops being weird. If anything, it's even weirder than the Ontos

I'd be more afraid of the driver than anything those guns deliver. That guy has a Grade-A mean face.
Five per platoon, three platoons plus two command vehicles per company for a then-standard formation of 17.
Okay, so it did use more units, though I didn't figure it'd follow the natural lineup. Still, 25 man platoons aren't that terribly large (don't tell the Marians that). Follows the same organization as my tank forces, the "old" format from
https://www.orbat85.nl/.
Used the same ammo and could use the same full lineup in theory, but was really outfitted with HEAT and HESH rounds only, not with any AP/APC shell.
Surprised and not surprised; HEAT was all the rage at the time but you'd think they'd load some solid shot in there. I suppose that's more of a doctrinal thing like the Matilda basically never having anything but AP for the 2pdr gun. The rounds exist, they're just not used, at least not in German service.
I do see the problem of having an open-air launcher, but that's going to be a thing for ATGMs in the era for pretty much anything. BMPs have to break their seals to reload the Malyutka, the YP-408s aren't even sealed completely, the Raketenjagdpanzers had to open up the roof...same goes for the mortars, for that matter. I do kind of want a dedicated TOW carrier for the antitank platoons, something bigger than a Malyutka or Milan ATGM.
Jaguar 2 was of very dubious usability in the then-current battlefield, lacking real NBC protection, being unable to reload under armor and not fitting secondary armament. Realistically it was simply a much cheaper follow-up programme to the Jaguar 1 conversion of RakJgPz chassis to fill up numbers.
I suppose I'll stick with Kanonenjagdpanzers then. RakJgPz 1 could reload under armor, right? They'd still break their seals as far as deploying the weapon goes, wouldn't they?
