The New Atlas is pretty good, maybe not leftist but certainly anti-imperialist. Since the start of the SMO he has mostly focused on that, and some US/NATO adventurism elsewhere.

Socialist Rifle Association has a YouTube channel.

I would suggest SRA, but you can tell with their content that they're walking on eggshells, so most of what they have to say is way too thin to be useful.

I'm not aware of a single left-leaning mil or firearms -tuber, and I suspect that's because open leftists in that sphere would be at a higher risk of death threats and investigation. If you can stomach the far-right or the right-liberal guntubers, they usually know what they're talking about when it comes to the subject matter (just know that they're going to make horrible """jokes""" or openly advocate for terrible things)

unfortunately, all of the """unbiased""" miltubers took a hard turn into NATO defending when the Russo-Ukrainian war started. And the same is true of all of the Eastern-bloc-themed guntubers, outside of the ones who actually live in an EB country... but a lot of them were pushed off of youtube by google for being Russian.

Although I'd say these channels are more accurately described as apolitical analysis based on facts.

• Cabbage did a 3 video deep dive on the QBZ-191.

• Red Effect covers tanks.

• Eurasia Naval Insight covers warships and planes in the pacific.

• Kalibrated with Scott covers Ukraine.
