I don't think that's correct

In an effort to increase accuracy some snipers resorted to use of the heavier .30-06 M2 armor-piercing round, a practice that would re-emerge during the Korean War.[22] Others sought out lots of M2 ammunition produced by Denver Ordnance, which had proved to be more accurate than those produced by other wartime ammunition plants when used for sniping at long range.[23] With regards to penetration, the M2 ball can penetrate 0.4 in (10.16 mm) of mild steel at 100 yards (91 m), and 0.3 in (7.62 mm) at 200 yards (180 m). M2 AP can penetrate 0.42 in (10.67 mm) of armor steel at 100 yards (91 m). These figures come from army documents.[24] However, a test done by Brass Fetchers shows that M2 AP can actually penetrate up to 0.5 in (12.70 mm) of MIL-A-12560 armor steel from a distance of 100 yards (91 m). The round struck the plate at a velocity of 2601 fps, and made a complete penetration.[25]

That's not a particularly relevant "test" for a lot of reasons; starting with the range(s)

That test was done at what looks like 25 yards, unlike Airtech's assertion of 100 yards. It was done on frozen terrycloth as opposed to quilted, close woven heavy canvas like the North Korean uniforms. It was done on cloth soaked clear through and frozen, where the Korean Uniforms were most effective as armor when NOT frozen.

Your link to 30-06 data is irrelevant, because there was never any problem with 30-06, or British .303/.308/7.62 NATO. The Problem was solely with pistol-class rounds, like .30 Carbine (which uses a projectile .308 inches in diameter, like almost all ".30 caliber" cartridges,) at long range.

Like Vietnam era "flak vests" the Korean uniforms were most effective against shrapnel, but they could make a long-range shot from a .30 carbine (or other pistol-class round) survivable.
