Totally non sequitur, just an FYI for those who have no idea what we’re talking about in some other comment threads, the National Institutes of Justice body armor rating levels.  I wonder if Bishop Farrell would have ever gotten around to impugning those of his flock who make use of passive defense, as he did so often against active defense (firearms)?

Drat, I guess we’ll never know now.  Keep praying for our new bishop, whoever he may be.

BTW, Camper, this list more or less confirms that you are correct, Level IIIA is generally considered proof against most submachine gun rounds, which makes sense, since most subs fire 9 mm, .45, or similar handgun rounds, though at somewhat higher velocity than standard hand guns.  Also remember that all soft body armor is pretty much useless against pointy weapons like knives, swords, battleaxes, broad-point arrows, etc.

NIJ LEVEL I:

This armor protects against .22 caliber Long Rifle Lead Round Nose (LR LRN) bullets with nominal masses of 2.6 g (40 gr) impacting at a minimum velocity of 320 m/s (1050 ft/s) or less and 380 ACP Full Metal Jacketed Round Nose (FMJ RN) bullets with nominal masses of 6.2 g (95 gr) impacting at a minimum velocity of 312 m/s (1025 ft/s) or less.

NIJ LEVEL IIA:

(Lower Velocity 9mm, .40 S&W). This armor protects against 9mm Full Metal Jacketed Round Nose (FMJ RN) bullets with nominal masses of 8.0 g (124 gr) impacting at a minimum velocity of 332 m/s (1090 ft/s) or less and .40 S&W caliber Full Metal Jacketed (FMJ) bullets with nominal masses of 11.7 g (180 gr) impacting at a minimum velocity of 312 m/s (1025 ft/s) or less. It also provides protection against Level I threats. Level IIA body armor is well suited for full-time use by police departments, particularly those seeking protection for their officers from lower velocity .40 S&W and 9mm ammunition.

NIJ LEVEL II:

(Higher Velocity 9mm, .357 Magnum). This armor protects against .357 Magnum jacketed soft-point bullets with nominal masses of 10.2 g (158 gr.) impacting at a velocity of 425 m/s (1,395 ft/s) or less and against 9mm full-jacketed bullets with nominal velocities of 358 m/s (1,175 ft/s). It also protects against most other factory loads in caliber .357 Magnum and 9mm as well as the Level I and IIA threats. Level II body armor is heavier and more bulky than either Levels I or IIA. It is worn full time by officers seeking protection against higher velocity .357 Magnum and 9mm ammunition.

NIJ LEVEL IIIA:

(.44 Magnum; Submachine Gun 9mm). This armor protects against .44 Magnum, Semi Jacketed Hollow Point (SJHP) bullets with nominal masses of 15.55 g (240 gr.) impacting at a velocity of 426 m/s (1,400 ft/s) or less and against 9mm full-metal jacketed bullets with nominal masses of 8.0 g (124 gr.) impacting at a velocity of 426 m/s (1,400 ft/s) or less. It also provides protection against most handgun threats as well as the Level I, IIA, and II threats. Level IIIA body armor provides the highest level of protection currently available from concealable body armor and is generally suitable for routine wear in many situations. However, departments located in hot, humid climates may need to evaluate the use of Level IIIA armor carefully.

NIJ LEVEL III:

(High-powered rifle). This armor, normally of hard or semirigid construction, protects against 7.62mm full-metal jacketed bullets (US military designation M80) with nominal masses of 9.7 g (150 gr.) impacting at a velocity of 838 m/s (2,750 ft/s) or less. It also provides protection against threats such as 223 Remington (5.56mm FMJ), 30 Carbine FMJ, and 12-gauge rifled slug, as well as Level I through IIIA threats. Level III body armor is clearly intended only for tactical situations when the threat warrants such protection, such as barricade confrontations involving sporting rifles.

NIJ LEVEL IV:

(Armor-piercing rifle). This armor protects against .30–06 caliber armor-piercing bullets (US military designation APM2) with nominal masses of 10.8 g (166 gr.) impacting at a velocity of 868 m/s (2,850 ft/s) or less. It also provides at least single-hit protection against the Level I through III threats.

Level IV body armor provides the highest level of protection currently available. Because this armor is intended to resist “armor piercing” bullets, it often uses ceramic materials. Such materials are brittle in nature and may provide only single-shot protection since the ceramic tends to break up when struck. As with Level III armor, Level IV armor is clearly intended only for tactical situations when the threat warrants such protection.

I’m not going to post your article but I understand it. Just for the record fellas I’m sure your aware Big Brother is now watching this.
I cant post your article because I find it interesting but I’m a peaceful Pro-Lifer and I don’t want it misunderstood. I’m sure as a fellow Catholic you will understand. Great Grandfather served WWI with his sons, his Grand children served in WWII so I understand. I also don’t want them thinking your bad. I don’t believe it. I think your well informed about ammo. God Bless though.
