turns out that normal people don't want to be around places unmoderated and unmoderable by design, and instead it's a magnet for nazis, pedos, nazi pedos and cryptobros, but i repeat myself
i mean, mostly i wanted to say that what you can do with 203 you can also do with two or one 155. there's many more of the latter, these are generally more modern, more accurate, have longer range and higher rate of fire, are newer, have better logistics supporting them already; and one soldier can be expected to handle a 155 but not 203. all of these are reasons why major militaries switched to single calibre like 155
in terms of warhead weight, other 90kg-ish weapons are sdb and gmlrs, of which gmlrs has a bit more explosive because of newer materials used and lower mechanical constraints (less acceleration during launch) and sdb has less for other reasons. these are more expensive, but also guided. there are also shaheds with similar size of warhead
i was also under impression that western 203 supply was depleted by ukrainian 2s7s. presumably it was relatively more available when 155 shortage happened, including cluster variants
it has only 25km range, 2s7 has 1.5x that, and 203 is only 2x as destructive as 155 with design of similar age, and the difference is smaller for new 155s
i don't envy ukrainian logisticans either even if pion fires the same ammunition
go to bed grandpa, A2A is missiles these days, with APKWS for shahed hunting (19 per pod. F15 can carry four). (not rockets (unguided)) if you want to use guns against them for some reason, then whatever it is must be slow to be practical, and guess what, we already have a tool for that: it's called helicopter. there were two F16 lost in Ukraine when they tried to shoot down a shahed with a gun iirc, they were damaged by shahed fragments. no reason to get too close when sidewinders or APKWS exist
A10s are limited to flying over iraq targeting militias there (with jdams/sdbs) last time i've checked. any of more modern jets can carry enough SDBs to last for all CAS needs, there are also heliborne APKWS and hellfires. nobody needs brrrrrt these days
it's not a twenty year old paper, it's a twenty two year old preprint which has all the reliability of a blog post. in 22 years, you can get born, complete all education bachelors degree, start masters degree and write a real paper that would be accepted in a real physics journal. the reason it's not accepted for all these years is it is packed full of crackpot nonsense. it cites Dan Brown's Angels and Demons ffs
you're designated wingman /s
