Its not a jackal. It's a MWMIK.
(Yeah I know)
As to the Deathtrap thing, its not designed to get in a bust up up close and nasty with Terry. Its a fire support and Recon Vehicle. Meaning its got lots of Guns and mobility.
I think your confusing several issues here. Snatch Rover's where being used in Iraq, and really where a death trap when hit by IED's. These where replaced with Mastiff, and In the RGJ, Bulldog.
The Land Rover WMIK has not had any serious problems in AFG or Iraq. MWMIK is designed to give WMIK rover's more fire-power. Use them at long range to clobber enemy units and stay at long range with them. Their Survivability is also helped by the fact Terry can't shoot straight 99% of the time.
