Anyone else noticed the T-90 tanks in the Divide, Su-25 Frogfoot attack aircraft & the various Antonov transports at the Mothyards? Have to say it's a little strange humanity was still using these obsolete vehicles during our so called 'golden age', just looking at the positioning of the tanks seems to show that they were used in the defence of the cosmodrome during the Fallen assault. We had colonies on Venus, Mars & the Moon, we had artificial intelligence etc. And we were apparently still using 20th century tech. Might be a little 'nit-picky', but I've always been interested in lore, even if the game is a little short on that unless you delve into grimoire.
Considering how many of them are piled up in seemingly random, un-airfield like locations (the giant group in the background in the Mothyards), I can only assume that these areas may have been scrapyards even before the Collapse. Its also possible that the Cosmodrome as a whole was a very early Golden Age facility, judging by the hulking, impractical colony ships and dated computers.
