Can they survive an IED?

[riverrunner]

depends on how big the IED is.

That was the primary requirement that initiated the replacement of the HMWWV.

The obvious higher ground clearance is a key characteristic to dissipate blast

In terms of UBB (Under Body Blast) protection, air is a cheap and potent help. As illustrated below, the distance between the source of an explosion and the truck is critical, as pressure decreases rapidly as a function of distance. So every inch that can be afforded to increase the distance of a truck’s underbody from a buried explosive yields a major protection benefit.

Reflected Pressure vs. Distance From Burst Point for 20 lbs of TNT.

The JLTV features large tires and a suspension that gives its hull a high ground clearance, comparable to the approximately 2- to 3-ft ground clearance for MRAPs. By contrast, the HMMWV has a clearance of only about 14 inches from the ground to the bottom of its hull.

Can a Humvee?

A Hummer certainly couldn't if that is your standard of reference. An MRAP might if the IED is small enough. An M-1 might not if the IED is big enough.

Can they survive an IED?

My PANG unit spent a one year deployment in sh*thole Iraq. We mostly ran convoy duty,pulled security and overwatch. There is nothing that will not conceivably be knocked out by an IED. We happened to see an Abrams,two Bradley,a Stryker,various MRAPs and a few "up armored" Humvees get ambushed by IED's. We lost four soldiers. Sometimes it's "luck" and "Mr. Murphy" that wins the battle.
