create alias stanag_magazine -> magazine_(weapon)
Do not feel like wanting to (manually) nuke this unnecessarily specific tag.
The main problem is that a lot of modern rifle magazines that are not complying to NATO's standardization agreement look absolutely identical to the STANAG magazines - especially in context of details on drawings. They are all box-shaped, same 30-round capacity and slightly curved. Some of them has vertical indentations which resembled the default M16 magazines that became the basis of STANAG ones.
Therefore I consider having STANAG magazine tag is utterly redundant. Box or stick-like shape (for pistols and SMGs) is considered to be norm.
For instance, despite sharing the same 5.56mm ammo, capacity and appearance to several STANAG mags (some have waffle-like texture), the default Steyr AUG mag is not even STANAG-compliant.
