Topicality
This is addressed in @called2voyage's answer but I'll add the following:
I'm the author of the linked comment which includes:
...so I think it's a great follow-up question. Please consider just posting it as a new one and linking back here for background. It would only need to be a sentence or two max, and could use the same tags"
and the current tags include military, security and weapon which have been used 54, 19 and 18 times. While that doesn't prove anything it suggest such a question may be on-topic. Not all of those security and weapon questions are about shooting at bears after landing in the tundra.
already answered in a comment?
... in a comment, and it was answered...
Stack Exchange is about good answers to on-topic questions. Comments don't count, comments are to be considered ephemeral (temporary), receive less critical up votes and can't be down-voted, and due to low visibility and interest can be wrong without any contrary comments pointing it out.
In Stack Exchange it's always okay to ask a question even if you (think that you) know the answer. Asking it as a question is a way of confirming/validating something or finding out it's not right, and to find supporting sources we might not have known and are happy to learn about, and to ensure this is all searchable, findable and available to future readers as well.
To avoid the possibility of a "What have you tried first?" or "What research have you done?" just quote the comment that purports an answer, and simply asks "Is this correct? If so, how do we know?" and users will recognize/remember that fact-based answers should be supported with links, references, or in some special cases1, support can be augmented with specific personal knowledge.
1This varies between SE communities, but I've accepted answers like "No it doesn't (personal knowledge)" and "No it won't (I asked them)" based on large bodies of expert-level answers previously posted by those users.
Go for it!
Go ahead and ask so that the answer can be captured in a proper Stack Exchange answer, properly supported, and voted-upon. That's the Stack Exchange way!
