I absolutely agree that the FREMMs are overkill. However I am not sure about the D'Estienne d'Orves avisos and the german gun FACs. They are geting older and older. If you cgoose to put them in your inventory this means you will desperately have to replace them in a couple of years or so.
Of course if you insist on a ship of the aviso type you can put an italian Minerva as a flagship, but you can go without it. A Cassiopea or two would be a better solution. They lack the ability to bite the way the Minerva can, but are more versatile. If Bovania has the funds for that I sugest for up to 10 Combat boat 90 with Hellfire ATGMs or even better a ore advanced ATGM system. Put also up to 6 minesweepers/ minehunters and a small support ship plus some inflatable boats and you're good to go. Of course you will need two to four sea observation stations and some minor naval aviation, but the latter should be in the air force.
Also for the air force I agree that L-159 and armed PC-9 put together is not needed and has no point.
- up to 16 PC-9M armed with ATGMs, gun-pods, rocket-pods, up to 600kg of bombload and some type of recce pod. If you want you could integrate two Sidewinders.
- additional 4 PC-9Ms for training needs (you could skip them and use the armed units also for training)
- between 3 and 5 maritime patrol PZL M-28 Bryza's plus 2 to 4 more Bryzas for transport (it can operate from field airstrips and has the same engine the PC-9 has, too bad it has no anti-ship missiles. You can use it in combination with shore-to-ship missile batteries, otherwise you will need another type of MP aircraft and that raises operational costs)
- Once again if you have the funds for that you could purchase the modern EC.635 scout helicopter with armament (up to 10 units), otherwise buy some old OH-58D Kiowa Warriors, or Hughes.530 or Gazelles
- Up to 16 light utility helicopters (about 10 AW139 would be nice, but UH-1H-II should do the trick aswell)
- 3 to 5 maritime helicopters like the AW139
If you think you need a transport aircraft heavier than the M-28 you could put 2-3 CN.295 in the national airline to save costs.
For the army:
If you intend to also use it as a gendarmery force you will need civilian standart vehicles as DURO.III, some Mercedes-Benz G-class... If not:
Anyway you say the terrain is mountaineous and road conditions are poor. I would say you should skip any MBTs and light tanks. You could add some 30-60 second hand surplus BTR-80s to the inventory. Other than that lots of Unimogs, G-Wagens, ATVs, maybe some Pinzgauers.
Artillery should be towed. You will have to buy lots of ATGMs, SPG-9 (a special forces retired captain from my country told me it just kicks ass and there ain't a better solution) and MANPADS (I sugest Igla 9K38) plus ZU-23. Up to 24 9K37 Buk would be the best top solution.
Navy:
I chose the the D'Estienne d'Orves avisos and the German gunboats as they have extensive combat capabilities. More bite as you put it. Furthermore, modernisation of these would be a fairly easy task. The German gunboats and the d'Estienne d'Orves have the already proven Exocet missile (scurge of the British in the Falklands).
As for FREMMs being overkill, it's for superiority purposes, of course it's overkill. They would give Bovania a extremely modern missile frigate system.
FREMMs instead of the d'Estienne d'Orves class would have probably been a more appropriate suggestion, considering that the new frigates are replacing them..
I like the Combat Boat 90 idea.
Air Force:
I guess we'll have to agree to disagree.
Army:
1. Bovania is flat, Norland is mountainous.
2. BTR-80? Why would I choose that over the Boxer? Or the Stryker?
The Stryker has more variants than lego blocks, and can take on some tank roles.
3. If we're talking ATGM, Javelins are always a good option. As for the SPG-9, isn't that a recoilless gun? Maybe I'm wrong.
4. MANPADS is already covered by Stinger/Starstreak.
5. Mobile AA already covered by the ADATS, if a ZU-23-style AA platform is needed, then I'd opt for the Gepard FlaKPanzer.
I'm trying to keep Bovania's weapons strictly NATO so that my suggestions for Norland can be the opposite.
