[quote=@Foster] Yeah, teh 170mm gun is pretty much the NorkIranian concept of the 175mm M107/M110 203mm "long-tom" for long-range counter-battery/coastal-battery spam. From US experience with the 175mm, the small-bore long-range was decidedly less-accurate and was discontinued in favor of a new-fangled spammable guided rocket artillery concept. It's biggest success was in the 1970s [i]when the IDF used it to knock out Egypt's Theater-level Air Defense System[/i] due to its 40-50 km range. At least, that was before it became HIMARS o'clock (the original rounds for the M270 actually had less range). And we've got one on the beach. Using the 2S7 as an example, the Koksan's emplacement time would be in the order of 6 minutes. Also, [url=https://militarnyi.com/en/news/serbia-presents-heavy-203-mm-tsmb-mortar/]Serbia did a thing[/url] with some old Vietnam-era US 155mm towed artillery, they slapped it on a truckbed and rebarreled them as 203mm mortars. Basically a poor-man's short-range long-tom, it generally matches/exceeds the range of the Soviet 240mm in a package that basically re-used stuff in Serbian surplus. They also did a thing to the 9M14... turning them into a poor-man's TOW. (the 9M14's construction was already funky, as the original rocket-motor was in the midsection, they added an additional one in front of the warhead in tractor-configuration, and replaced the tail wire-guidance unit with a radio-controlled version [url=https://www.youtube.com/watch?v=DmsWVMGmK-I]so it could slap twice as far, twice as fast, and with twice the penetration[/url]. It's the one on the left, "normal" 9M14s are alongside [img]https://www.edrmagazine.eu/wp-content/uploads/2023/09/MTI-Malyutka-upgrades_01-800x534.jpg[/img] [url=https://www.edrmagazine.eu/upgraded-malyutka-antitank-missiles-ready-to-join-the-serbian-army]It's a great big chonking 30kg sky-torpedo when a normal 9M14 is closer to 15 kg.[/url] Iran's shooty-n-scooty are basic 155mm M109 and M109 derrivitives augmented with stuff like 160mm mortars kitbashed onto things. That or running-up and yeeting a tank round. There's also unguided rocket-spam but we'll assume HIMARS focused on suppressing that eldritch nightmare of friendly-fire.
