Perhaps. Although that's one boring Claymore knockoff.
The biggest sticking point, and a big one for an expeditionary army, is that land mines are a force multiplier particularly needed when you've got smaller numbers, and we and South Korea really need a lot of permanent ones on the border with the extremely murderous until the latest Kim DPRK.
(Ditto, but who knows when or if it'll happen, with our border with Mexico. Maybe Canada as well although infinity pajeets is a difference sort of threat, but if it becomes (more of) a PRC satrapy.)
See also cluster munitions, with their non-zero failure rates. One PRC/DPRK version I think with a particularly high failure rate just killed an Israeli teenager and wounded many more, was picked up by him or another idiot, put in a backpack, then not long after KABOOM.
