The Unsung Vietnam War Mod

Finally on Steam for the first time, this 14-year old mod is celebrating it's 5th update for Arma 3.
It is a full conversion mod for Arma 3, featuring 11 maps, 10 factions, 100 weapons, 1000 uniforms, 11 tanks, 20 trucks, 15 jets, 15 helicopters, 20 traps, 20 static weapons, Vietnam era music and radio, a fantastic Vietnam War atmosphere and intense jungle combat.

- The mod is 7.6 GB to download and 12.1 GB uncompressed
- APEX is NOT required for the mod.
- For maximum enjoyment, we recommend that co-op server hosts run a custom difficulty profile with enemy AI accuracy set below 0.2


Welcome to the Nam! You’ll soon be enjoying the suck as an everyday Marine or Soldier watching for traps and the many ambushes that wait for you in the Jungle, with an M16 or an M14 in your hand you have to be wary of every direction and up or down, looking for snipers in the trees or traps at your feet. Clear spider holes or tunnel systems, securing a victory through Hearts and Minds as Infantry, or enjoy yourself as a pilot in a fleet of old planes and helicopters! Fly a Huey jamming music through the jungle as you transport troops or do CAS missions, or fly a Jet running CAS missions dropping bombs or napalm on the enemy. Or do you fancy yourself fighting for the Vietnamese quest for independence? Play as the tenacious National Liberation Front, who the Americans call the “Viet Cong”, or play as the formidable North Vietnamese Army, you decide in The UNSUNG Vietnam War Mod!

The Unsung mod team, which has been working on this authentic Vietnam-era full game conversion since OFP (in 2003), brings you realistic jungle fighting, hand-to-hand combat and fully 3-dimensional warfare in this immersive standalone mod for Arma 3.


- Fight across 13 large and detailed maps, of which 5 use the beautiful APEX DLC foliage
- Join the fight with over 100 authentic period weapons, from AK47 / M16 to the more rare weapons like MAS36 or K50
- Ride into battle on the Jeep, M35 truck, M37 truck, M113, XM706 or M551 Sheridan or M48 Patton MBT
- Vietnamese vehicles include the Zil157, Ural, Type 55, BTR-152, T34, T54 and T55
- Patrol the rivers in PBR's, zodiacs or NVA patrol boats
- Blow away your enemies with over 30 types of static weapon, including artillery, AAA and SAMs - there's a calibre for every occasion!
- Fight as one of 15 factions including US Army, USMC, MFR, LRRP, SF, CIDG, Australia, New Zealand, ARVN, VC and NVA
- Test your helicopter piloting skills in the Hueys, Cobra, Chinook, Cayuse, Sioux, Choctaw, and Shawnee
- Engage your foes in the A1, A3b, A4, A6, A7, C1a, E2, F100, F105, F4e, and F111

Dependency and compatibility

The Unsung mod is designed as a standalone full-conversion mod for Arma 3. This release supercedes Delta release and is a complete replacement for it. It should be backwards compatible with missions made for Bravo, Charlie and Delta editions.

Some of the maps use APEX foliage and playing on those maps MAY cause you issues with signed servers if you do not have the APEX DLC. This issue is being worked on and we hope to make it non-Apex dependent VERY soon.

It is not tested with other mods, and we cannot answer questions about compatibility.
However we have tried to make it work with TFAR, and it probably works alongside ACE, but what works and what does not work with ACE is unknown.

If you have memory crashes using Unsung, especially on the APEX-related maps. Turn down your view distance, and play in 64 bit and test the 3 available memory allocators in the A3 Launcher.

You do need apex to run the maps correctly, correct?

we have 8 public servers up, i've added some of their IP's to the page above

good stuff. you may find a lot of height changes on vehicles, as we had to redo them completely for the physx. so planes may spawn 10 feet in the air and m113s may be under ground, so a bit of height adjusting to do in the editor mainly.

Oh I think it was just the uns_uniforms_base problem from above, its fixed now. Yeah there's just a few structural things to fix, don't really need a classnames list. I'm remodding the whole thing anyway into a newer version of DUWS-R.

Are there any busy servers active rn?
Eggbeast  [author] Nov 23 @ 5:20am 
i don't think we change any structures - a lot. might have been a lsight tweak to one or two. what's the problem?
LT.DANG Nov 22 @ 11:54pm 
Have you guys got an updated class names list, I need to fix/update my UNSUNG DUWS VIETNAM mission to echo. It looks like you've changed the structure of the factions a lot so it would be handy to get a hold of the new structure so I don't have to copy and paste it all out of editor........again.
