|When I first saw that improved versions of the LAW were being made I was excited.
Then I got to thinking... The LAW probably has about the same penetration through RHA as an RPG, ~12 inches. However, the venerable Energa 75 rifle grenade has penetration of ~15 inches.
Effective ranges of both are around 200 meters, though realistically the Energa has a direct fire range of more like 150 meters.
So, is the 50 meter more range of the LAW worth the 5.5 (versus approx 2 pound or less Energa) pound weight, and the over 2 foot closed length (versus about a foot for the Energa)? When you look at it the rifle grenade is generally less bulky as well, and doesn't leave a firing signature like I assume the LAW does. The M72E8 would leave less signature then the regular M72, but it would also weigh more. The M72E10 might... might... be better in the anti-personnel role, but then again a RG similar in size and weight to the Energa would be absolutely devastating at close range if made into a pure fragmentation type. I don't believe the Energa is a bullet pass through type RG, but with modern technology this could be solved as well.
What do you think? Personally I think its just to compensate for the lack of the 5.56's power, which correspondingly reduces rifle grenade range.
