I don't have any photos, but the IDF: since they do have their own arsenal of weapons [anything with IMI in it is IDF]. Specific vehicles could be the Merkava; which is a APC/Tank hybrid. Specfic calls could be for a spec ops team, paratroopers, medic team. Specific weapons, anything with IMI in it: IMI Negev, IMI Uzi, etc.

I've some non-fictional army's idea, but I still need to do some more research on it. However, in terms of fictional factions, I got an idea, the Combine military that is stationed on Earth in the Half-life series. Well, more like Half Life 2 and later games.


Faction name: Overwatch soldier


Inspiration pictures/infos:
http://half-life.wikia.com/wiki/Overwatch_Soldier
http://half-life.wikia.com/wiki/Civil_Protection


Weapons:


Base assault rifle: Overwatch Standard Issue Pulse Rifle
Light machine gun: HK21 (Not an actually in-game gun, it's just the game's beta concept before it was scrapped.), with 100 round rectangular box magazine, you probably never heard of it, but neither have I until I research about it, in the real world, they were no longer being manufacture.
Sub-machine gun: MP7
Shotgun: SPAS-12
Pistol: USP Match
Explosive ordnance: MK3A2 Grenade, C4 (There is no C4 in the game, but I assumed they have one)
Emplacement: Emplacement Gun (I'm sorry, this is what they actually called it, but to be honest, all the gun listed above, they were also named very vaguely in game.), Turrets (I don't know about this, is it possible to program an emplacement to become AI working for one faction?)


Armor:


Hardplate-reinforced personal armor


Vehicles:


Armored Personnel Carrier (Armed with rocket, and pulse rifle)


Calls:


-Overwatch energy artillery support
-Headcrab shelling (Which spawns Headcrabs)
-Timed Helicopter explosives (Which means that after the explosives were dropped on the battlefield, it will roll around and explode later.)


Additional info:


-About the in character models, if you only want put in what is from the game, I'm fine with it, but if possible, I would also like to see the beta and concept art model appear in the mod, they look so cool, but ultimately they never made it into the final product.
-If you also wish to insert the Civil Protection with the overwatch soldiers, it will be delightful, the only reason that I did not write it above is because the game and the lore make them distinguishable. The only difference between the Overwatch soldier and the Civil Protection are their character model, and Civil Protection usually uses the USP Match and Stun Baton, and they also wear combat armor (Which is a downgrade version of the Overwatch Soldier armor.)
-About the headcrabs, can you make them like the zombie currently in the mod, I'm not talking about the headcrab will infect a dead soldier on the battlefield and turn them into a zombie, but I mean the one hit kill mechanic.
-The reason that I add a non in-game gun is just because so we have a machine gun to play with, and one of the comment did suggest that I should add more weapons. But I have just only added one weapon to the list.
-The reason that I chose HK21 is because most of the weapon in Half-Life 2 are european weapons, MP7 is from Germany, USP match is also from Germany, SPAS-12 however is from Italy, and the Pulse rifle is from the...Aliens, I guess. So why not something bigger like the FN Minimi ? Well that's because to match the lore setting, Earth was defeated after 7 hours of Alien invasion, and to make sure that no effective mass resistance group will raise up against the Combine, all Earth weapon platform used by the Combine overwatch should be "look" light. So even if anyone kills a combine soldier and loot their weapons, it will be look less of a threat than having a giant machine gun that will shoot down the whole street. Some of you may think this reasoning is ridiculous, and to be honest I think so too, but if valve is not going to expand their own lore, I'm just going to do it myself using logic.

EDIT: I actually didn't see the comment above mine. My idea is scary similar to his...

+support for the combine

Before I write another comment about my next idea that you can pick from, I may want to suggest something I never thought of until just before I wrote this message, and it's instead of having soldiers holding guns, why not go medieval ? To those of you who don't know what medieval is, look it up, I don't wanna spend hour typing a history book. I don't know how it will work out, but it is an idea I just happened to come up with, and in terms of weapons, melee weapons, I know there are few, but not enough to write a whole post about it, so if anyone who like my suggestion and are medieval expert, feel free to grab this suggest and make it into your own, I would actually like to see what you wrote.

Alright, I think it maybe because of the first comment that I wrote that casue me to do this, but now I'm just going to give out the names of the factions that I think should be added into the mod, because I'm kind of tired of researching and editing my responds, so here we go:

-Imperial Guard (Warhammer 40K)
-Joint Strike Force, European Federation Enforcer Corps, and Spetsnaz Guard Brigades (EndWar)
-Human (UNSC & Insurrection) & Covenant (Halo) (I know there used to be a mod that have all of that in it, but the developer seems to dropped the project, and the new Halo mod in steam workshop looks promising but haven't deliever it yet.)
-COG and Locust (Gears of War)
-IMC and Militia (Titanfall)
-Krone Guard soldiers & Resistance (Timeshift)
-SATO & SDF (Call of Duty: Infinite Warfare)

A mod like the one you wish exists. I think it was dropped, but it was called "War of the Roses" mod in the Running With Rufles forums. It was medievil, but that was from months/years back. It may be updated, it may not, idk, idc.

Faction name: United States Army (USA)

Support
---------------
Paratroopers : Call in a staged combat drop of a platoon-sized unit of paratroopers from the 82nd. Airborne Division, or the 173d. Airborne Brigade to assist groundside Infantry.

Artillery: Call in combat support from off-map artillery batteries to pepper your chosen target with steel rain. This support system could be used in a multitude of different ways: (I.E. Different fire-mission sizes. 1 round, 4 rounds, etc.).

Air Strikes: Call in a designated Air Strike from a circling A-C130 Gunship to salt the earth with harrassing fire from a 40mm cannon. In addition, you would also have the option to call upon the aid of an AH-64 Apache Gunship to provide CAS with Hellfire rocket pods.

Additionnal info: Well, we have those Marine guys already...*cough*jarheads*cough*...and i thought to myself: "Hmm...what could be added to this already outstanding mod? We have these awsome factions like...those guys. Oh, and those! Hmm...I know! What about the premiere land-based fighting force of America's military?" And, here we are. Being an Army brat myself, I certainly wouldn't mind seeing this as a reality within this mod. As such, i've taken great care to make sure that the sources i've listed above are as up-to-date as possible; with most weapons, support calls, and vehicles being accurate to what's in service today. I hope you consider my idea for further updates. Thank you for your time.

P.S. Great mod. Keep up the good work. ;)

I also add my support to the Combine, heck you could even modify the Clear Sky to be more high tech and name them that.

+support for plagf

First of all I want to say this mod it's fkn awesome.
Faction name: United Latin American Forces (ULAF)


Inspiration/pictures/info
------------------------------------------

Well this would be a union between all the countries of Latin American, in the photos I put armies of Argentina, Colombia, Mexico and Chile.
It is to add to the conflict armies around the world.

I hope you like the idea.

I don't own the game, really thinking of getting it. How about the other factions from S.T.A.L.K.E.R.? I saw that you already have Clear Sky. Stalker theme maps, mutants, anomalies etc would be so coo!?

Hi all,
First I want to thank you all for your proposal, I really appreciate that you spent some time to write your ideas down here!

But for now on I'm struggling to find some help because I don't want to invest more time on new factions if I can't make them right. I mean that there's no point to make IDF if there's no custom models for the vehicles, no point to make some WH40K armies if we don't have custom maps to fit with, STALKER factions if I'm unable to code some gameplay mechanics alongside...

I Really want to improve my mod, for you players as well as for my own pleasure, but I want to keep it coherent, and I don't want to see some 70's vietnam troops fighting in sand maps against some Halo troopers... If I manage to get the help I need I'll work on casus belli as well as side projects with pleasure, trust me!

If I get a team to work with I'd like to implement the IDF, the PLAF, and a mix of Stratus Organisation and ARCOS. If we manage to have custom maps sets in tropical environnement I'd be glad to add the United Latin American Forces...

But once again, I need help to achieve this...
