What a bizarre way of viewing warfare holy shit. You're not going to be dropping JDAMs on IFVs for very long when you're fighting a nation that has 40,000 of the fucking things and builds a hundred every month, and also has actual air defenses to shoot most of those down before they even make it to their targets
The Lancet is probably one of the best pieces of equipment to be rushed into widespread usage in a real war, ever. It can act as artillery and participate in counter-battery fire, it can harass infantry and its existence alone causes panic, it can be used as a tool to kill singular soldiers in trenches, it can easily destroy IFVs, APCs, trucks, jets and planes parked in runways, it will destroy any tanks that the enemy abandoned without forcing use of an ATGM or anything that would leave soldiers more vulnerable, it can sink boats that are being used by sabotage groups to cross rivers, and it can be used as a tool to harass (and even destroy) tanks. 60% of the M777 howitzers given to Ukraine and destroyed by the Russians were destroyed by Lancets.
The fact that the Switchblade is a piece of shit (it costs fifty fucking thousand dollars to make, which is hilariously inflated - the Lancet costs 35,000 and it's actually been proven to be good) that the US didn't bother making in any relevant number doesn't mean that suicide drones or loitering munitions (which are essentially just cheap guided artillery anyway) are "mediocre/not-so-impressive weapons". I can already tell the US is going to learn absolutely nothing from this war if this is the thinking in western circles.
