Referencing to recent leaked report about Ajax IFV, british vehicle that entered service in 2025.
Its easier to name whats NOT problematic in it, than what is. Previously troops that were inside it on the move became nauseous, which at first was fixed with better headphones. Turns out it didn't fix anything and there is whole pletora of other problems, one of which I mentioned above. And thats after 15 years of development.
