You may want to look at this Wikipedia article on the 1975 reform of the Italian Army which formally abandoned regiments (previously traditionally triangular organized in homogenous fashion).
Oh GOODY. And it even has links to the structure in 1974 and 1977 to compare with. Not to mention 1975, ha ha, perfect timing.
Well, I was thinking of detailing the force structure changes. Maybe Kato's list is how things start in 1974, and then I'll end up with a major modernization program beginning then, pick new programs that started initial development in 1975/76, and use that to create a 1990 version as things settle out.
The great "breaking of the regiments" as it were, that ought to be fun. At an initial glance, stripping the regiments down - maybe keeping the name at least as a bone to the traditionalists - into their various companies would dramatically reduce transit time and make for a better fast-reaction capability, along with an emphasis on mechanization across the board perhaps.
Or maybe go backwards, strip the mechanization, and convert all to light infantry because why not be stupid at the same time you're smart. (Kidding! Maybe)
Hm...building combatant regiments off of four formats: armored cavalry, light cavalry, heavy infantry, and light infantry.
Possible option could be a "general fire support battalion" with e.g. 4 batteries of 6 guns and a second that provides "specialized fire support" with e.g. 2 batteries with 16 light MLRS, 1 battery with 105mm (for the light infantry in the division) and 1 battery with something more specialized such as battlefield surveillance drones (examples: CL-89 since the 60s, MBLE Epervier in 1977).
With four batteries of six, I suppose one battery of heavy mortars, and three batteries of 155mm towed or SPG? Or would mortar carriers be better slotted into the mechanized battalion directly?
I suppose I should also detail what's available at divisional level, would that be another attached artillery rgt, this time with 203mm and/or heavy rockets?
The one thing that keeps sticking in my head on the Grad is less "40 122mm rockets per launcher" and more "three minutes to set up, one minute to fire, ten minutes to reload, two minutes to pack up and skedaddle" mobility. I'm sorry but I REALLY like that, even more than its firepower capability; the fact it's been in production so long...I can see an inordinate amount of these things just sort of stuffed into every depot's nook and cranny and nobody understands why they keep appearing.
In fact there's not even a contract to produce them anymore, so they say...which means the Grads, in the dark corners of the lagers, are quietly breeding like tribbles...
On the topic of mortars, MT-LB 2S24 had an 82mm mortar onboard with 83(!) rounds of ammo, while the Bulgarians had a 120mm variant with 58 rounds onboard. I could absolutely see using those in the same role as the suggested M113.
Shame there's not a towed Grad launcher; I almost want to invent one but I'll settle with fluff saying weird licensing issues said it could only be built with the truck based system, and use the MTLBs to tow tube (or mount it, hello 2S1) instead.
Idle artillery question. Mixed 105/155 or all intermediate 122? Pros and cons of both?
