Has there been any discussion of various orc cultures and armour/weaponry. One of the things I think worked really well about the Jackson films was how easy it was to identify not just orc arbour and weapons from those of other races, but also to differentiate between orc groups. And also detailing spoke to culture in ways I’d not considered. Having black speech etched into leather opens lots of questions about skill and construction. Do we ever address orc society and family groups. Are orc weapons ever passed on? Are they issued out? Do certain orcs act as blacksmith or do individual orcs fashion their own weapons? Which begs the question whether their is even uniformity to the designs of weapons and armour? And are all those topics different for different subsets of orcs?
At this time, the Orcs are a pretty uniform group. They're all stationed in and supplied from Angband. This would make the idea that they are constructing their own weapons and armor pretty inefficient. There would likely be a smithing and labor class, alongside the captive slaves in Angband.
As to family groups, we've left the question of Orc reproduction more or less unanswered. If left up to me, I would say that during this time, and likely until the defeat of Morgoth in the War of Wrath, there are no Orc families. Young Orcs are raised and "cared for" collectively. Later on, there might be family structures as the Orcish diaspora occurs and before Sauron rises to power.
So for right now, there are likely specialized armors and weapons for specialized soldiers, but all armor and weapons are made from the same set of specifications. There will likely be different sets of insignia for different units for the sake of organization.
Now, there will be a change in S06. For the first time, there are Orcs stationed in places other than Angband. Tol-in-Gaurhoth and Taur-nu-fuin are good examples of this. They may have their own manufacturing centers to protect supply lines, but the question is whether or not enough time passes for them to innovate their own designs. I'd argue that this does happen in Tol-in-Gaurhoth. Whether it happens in Taur-nu-fuin, I'm less certain.
