My suggestions:
Spanish MARTE helmet
Bulgarian M36
Your typical Warsaw Pact Y-Strap (pls make them CWR3 compatible)
UTV webbing
M33 (Covers)
NVA officer uniforms early (50s&60s)
Italian field cap (Similar of that of the BW feldmutze)
Chinese uniforms with olive drab puttees

Casio F91-W watch
They have been very common since they were introduced in 1989 and watches are a cool detail to add to loadouts. Would be cool to see them in the facewear and nvg slots so you can wear them with other stuff :)

I second the Rhodesian and South African rigs, literally no good mod for them.

Here is a interesting suggestion, have all the rigs and vest also be as backpacks for kitbashing fun.

Hell yeah

French TAP Webbing might be a good shout, as well as some of the older Mle 1935 webbing they issued with leather pouches.

Would be awesome to have variants of the chest rigs and webbings like grenadier, medic, sapper and squad and team leader versions of the chest rigs and webbings.

Obr.69 (VFM and VDV included)
British 60s 70s uniforms
British MK3 helmets

At least one NATO style uniform and webbing, either late/early cold war. I get that this is supposed to complement GM but with those it would allow playing scenarios without it which is what my group tried today and had to do with CUP & 3CB which is why I got this idea. It wouldn't have to be a specific country but rather in the style of NATO post-war copies of US M1943 like the below in the Dutch, Norwegian and Danish armies. S&S has the Dutch M58 uniform and their P37 webbing which is what I have in mind more or less.

@OokamiJamie could you add more textures for the 6b3 body armor? Like a darker green, a tan, and a weathered white. These models are amazing when creating custom faction with ALIVE and it would be perfect if their was more variety to work with.

Yugoslav M-1 Gas Mask

More variation to 6B3 vests mesh - belt was typically used to carry an extra pouch on right hand side, canteens on the back, etc.
Mod already has soviet Y-rigs, these bits can be kitbashed from them

Portuguese Colonial War gear would be super cool. The M40 helmet, their weird webgear, lizard-camo uniforms... I have a huge huge huge amount of visual references if that's a thing you'd wanna do~
