And yet evey nation on earth is continuing to build and upgrade ifvs, because they provide a lot of fire power and mobility organically to infrantry units, gust like mi-24, if anything there getting more popular as wars that need big tank battles drindals these days go down and wars focusing on infrantry battles gos up. Whether that means the mi-24 is still a good idea ¯\_(ツ)_/¯ but russia at lest seems to be in zero hery to change or get rid of them like they are whith there missiles, airforce, or armord corps.
But that’s the thing, IFVs are used for their own very specific purposes. Any army proposing to use IFVs as a general substitute for trucks would be a laughing stock. Some armies do use them
instead of tanks, but that’s because they are either too poor to afford tanks or don’t need the firepower. IFVs properly belong in a balanced force, next to tanks and in front of a fleet of trucks.
The analogy also isn’t perfect because an upgunned transport chopper can fulfil a big chunk of the firepower component which a truck cannot.
The Mi-24 is a bit of an odd beast and while it makes for a perfectly decent gunship, and is presumably much cheaper than the Ka 50 / Mi 28 or western equivalents, in retrospect they would probably have been better off stripping out even more of the transport features. Something like a supersized Cobra with the same systems as the Mi 8/17 to operate alongside them.
I think it’s notable that both the later sov/Russian designs and the Sikorsky equivalent ended up in basically the same place - a big beefy pure gunship with a few nooks and crannies in the fuselage that can be used to stuff things into, but they are not transports any more than the Merkava is an APC/IFV.
