TSLRF upgrading his body armor I've been thinking about doing the same. Hurricane Sandy and the news coverage was a bit of a prompter too. Body armor saves lives, it is a big deal. We currently have soft vests which are good against most threats, and a K-30 trauma insert upgrade which gives very economical protection against some carbines (like, M1 carbines) and oddball "PDW" rounds, but the next logical step is some sort of rifle protection. A thug gunned down a trick or treater in our community a few years back with an AK so that sort of threat is certainly out there.
USES AND CRITERIA
The #1 application I envision for body armor is dealing with a home invasion type scenario. The #2 application would be "low profile" usage (under a sweatshirt or something) during movement in a vehicle if things got really squirrely (evaccing in a Katrina type scenario, for example). The #3 application would be extended wear in a static position while watching the house in a "shelter in place" type situation. I do not realistically expect to be conducting long range patrols on foot or anything in my kit. If there is a serious disaster I will be sheltering in place or traveling in a vehicle away from the affected area. Finally, these plates will be moved around, stored in vehicles, etc so durability is important. Therefore, durability, profile (thin), and protection are more important to me than weight.
I compared each of those criteria against each other using pair ranking and decided on the following weighted values of importance to me:
- PROTECTION: x4
- COST: x2
- PROFILE: x2
- DURABILITY: x2
- WEIGHT: 0 (but I will give it x1 points as it does have some value as a consideration)
The trick is figuring out what the optimal curve between cost and utility is. I've sorted it out into a few categories. I'll evaluate each category against my criteria then apply the above multipliers.
HYBRID TRAUMA PLATE
Midwest Armor makes the Mass III ($209/1.3 lbs) and
American Body Armor makes the IMPAC-RT PLUS ($160/3.2 lbs). Both come in 5x8" sizes that would fit in the trauma plate pack on a soft vest or carrier.
The Mass III is rated for 308, 7.62x39 AK, and non-armor piercing 5.56 (up to M193). The IMPAC-RT PLUS is rated for the same threats plus M855 (surprisingly!). The downsides to the IMPAC-RT are a steel core and the subsequent risk of spalling, along with some weight.
- PROTECTION: "-4." These products are not NIJ tested. They do not cover AP threats. I am also concerned about spalling from the steel core IMPAC-RT. They're small and don't fully cover the vitals.
- COST: "+2." By definition I can only wear a front plate and they use my existing vest. I can also repurpose them into side plates later, saving funds down the road if I get a more robust set up.
- PROFILE: "+2." It doesn't get much more low profile than fitting into a soft armor vest.
- DURABILITY: "+0." These are new products so there's not much data. The steel IMPAC-RT should be pretty rugged.
- WEIGHT: "+1." About as light as it gets.
TOTAL SCORE: +1
CHEAP STEAL PLATES
I picked up a 5.11 plate carrier awhile back when it was on sale for a ridiculously good price. Sure, it isn't the best or fanciest but for a basic home defense rig it'd get the job done.
Going along with the el-cheapo rig I could throw in some steel plates ($100/8.6 lbs each). All weights cited are for 10x13" or something close. Or just one steel plate. For a "DIY" spall guard, I could get a 3A vest remnant "not for defense of life or property" for twenty bucks or so and slap that in front.
The weight concerns can be mitigated somewhat by going with a smaller size.
- PROTECTION: "+0." They do not cover AP threats and spalling is a significant concern. I almost gave this a minus due to the spalling issue but I think it can be mitigated to some degree.
- COST: "+2." The cheapest option by far. They can also be repurposed for limited vehicle armor (stick 'em in map pockets, for example) in a "driving out of dodge Crazy Katrina" type situation.
- PROFILE: "+0." They're actually surprisingly thin, but they need to be worn over a 3A vest, with a spall guard, and in a plate carrier.
- DURABILITY: "+2." I think you could drop this off the roof and the steel plates would be fine
- WEIGHT: "-1." The heaviest option.
TOTAL SCORE: +3
LEVEL IV STANDALONE
Again I can use my existing cheap carrier or purchase a new nice one for $150 or so (+/-$50). Level IV plates run from $150 to $220 or so depending on size, cut, etc. They are also heavy at ~8.3 lbs each and fairly thick at 0.75".
- PROTECTION: "+4." Clearly the best protection.
- COST: "+0." Sort of a middle of the road cost option. They could theoretically be repurposed for vehicle armor as well.
- PROFILE: "+0." One of the thicker options, and requires a dedicated plate carrier. But, the saving grace is that they do not require backers or a supporting vest.
- DURABILITY: "-2." Ceramic plates are not as fragile as some claim but they do need TLC and inspections.
- WEIGHT: "-1." Almost as heavy as steel.
TOTAL SCORE: +1
LEVEL IV SUPPORTED
Level IV with 3A vest supporting plates seem to run about $250 but weigh 7.5 lbs while being a half inch thick.
- PROTECTION: "+0." No AP protection. Still, the requirement to wear wrap around soft armor will increase protection to some degree against pistol/shotgun/shrapnel threats.
- COST: "-2." More expensive for less protection.
- PROFILE: "-2." Not much thinner and requires a supporting 3A vest to boot.
- DURABILITY: "-2." Ceramic plates are not as fragile as some claim but they do need TLC and inspections.
- WEIGHT: "-1." Obviously the worst when you factor in the weight of the 3A vest.
TOTAL SCORE: -7
ULTRALIGHTWEIGHT
The MASS III weighs in at 3.3 lbs, is 0.75" thin, and a whopping $479 per plate. It stops non-AP threats.
The Mass III plus is 1.25" thick, 5.2 lbs but will stop AP 5.56. It also runs $479/plate.
BulletProofMe looks like they have a product very similar to the Mass III lineup for a little cheaper.
- PROTECTION: "+0/+2." No NIJ rating on the MASS vests. The variant that stops 5.56 AP gets a partial "plus" here -- not the full +4 of a legit level 4 plate but still a stronger swimmer.
- COST: "-2." Super expensive.
- PROFILE: "0/-2." The baseline MASS vest is equivalent to the standalone ceramic plate. The AP version is one of the thickest considered.
- DURABILITY: "0." Should be more impact resistant than ceramic, but still a new product.
- WEIGHT: "+1." Obviously the best. If walking around all day in armor was important for me this would be a big priority and the MASS plates would look awesome assuming I had infinite money.
TOTAL SCORE: -1
FINAL TALLY:
- Steel: +3
- Upgraded Trauma Plate: +1
- Level IV Standalone: +1
- MASS: -1
- LEVEL IV Supported: -7 (!!!)
These results are definitely surprising, in that steel does so well based on my criteria. You could argue that steel deserves a worse protection rating: while it covers a larger area than the trauma pads, it is still only level 3 and the spalling issue is worrisome. If I don't opt for steel, then the choice is pretty clearly between concealability and economy (upgraded trauma plates) and protection (level IV standalone). That's kind of a tough call, honestly. The compromise might be to go for Level IV but only get the front plate. That should be sufficient for most defensive situations while keeping costs comparable.
