@@Privateer91 thank you! This one didn't take me long to do at all because I had already covered the radar usage and missile symbology on other tutorials. My next tutorial might take a few more days to come out, as I'm planning on making it about a more complex topic.
Good question, I'm not sure how it is IRL, I'd say it might depend on the block or the specific version for a country. For example, apparently the USAF Vipers weren't equipped to carry Harpoon or at least it wasn't very widespread, but other air forces had most/all of their Viper fleets equipped for this capability. About the Sparrow, this version block of ROKAF Viper can carry 4, and considering BMS' tries to be realistic I imagine it's based on some source.
