In 3.x , most military used a same model for military vehicles and outfits , what has annoyed me was to see totally differents armies use the same tank . To make it shorty, I think each country should have military vehicles based on it’s real counterpart , Russian based map could have T-90 / T-72 like tanks while Americans based map would have M1 Abrams, well you see what I mean .
While it could take more time for models, I think it would definitely bring diversity and a better feeling in the game .
Same does apply for outfits, all had the same bulletproof vest, same shirt, pant, etc… while each army has it’s own . The suggestion would be to make Unturned counterparts of the real outfits . Basically , a US marines / ranger outfit shouldn’t look like a recolored spetsnaz outfit , some mods such as special forces pack and more military vehicles did this on Unturned and I can guarantee the feeling was here .
Finally, last suggestion was a camo pattern / paint , basically, each vehicle got parts made of colors on which you can’t paint ( like exhaust pipes , steering wheel ) and parts on which you can paint or apply a camo , the body of the vehicle , holding the mouse when looking at the vehicle with paint / camo pattern would slowly apply the chosen pattern / paint .
Basically, when holding a urban pattern and looking at a vehicle , you could apply this pattern on that same vehicle .
