Cougar MRAP vs Navistar MRAP

If the US Army's Cougar MRAP is a wolf, the US Department of Homeland Security's Navistar is more like your family pet dog.

The US Army is phasing out their Cougar 6x6 Mine Resistant Ambush Protected (MRAP) vehicle - and they're being transferred to the US Marine Corps.

Cougar MRAP
While the Cougar MRAP is far more survivable than the venerable HUMVEE, as you can see below, they don't hold up all that well against a roadside bomb. I suspect that is why they're going to the US Marine Corps. The Marines have a history of inheriting equipment from the Army. (LINK - Download a brochure)

The US Department of Homeland Security has a far less capable MRAP as seen below. They currently have sixteen of these urban assault vehicles (not 2,700 as has been reported). (LINK - View a brochure)

Navistar MRAP - the choice of the Department of Homeland Security

MRAP vehicles are good in urban environments or in many desert environments, but they are so very heavy that they bog down easily in mud or in wet/forest environments. As with any piece of equipment, they have advantages and weaknesses. The weight of metal that protects them also acts against them in some situations, bogging them down. Neither can they operate in high urban threat environments where their opposition is armed with rocket propelled grenades (RPG-7) or other armor-defeating munitions, unless dismounted infantry moves through they area before they do and clears it of insurgents.

In most law enforcement situations, (zombie war scenario) where their opponents are untrained and/or lightly armed, the Navistar and Cougar MRAP's are fine - and they do represent a less mobile but far better protected choice than a Humvee.

HUMVEE ADVANTAGE vs Navistar

The Humvee handles much better on icy or slick roads, on muddy roads and on terrain that is difficult to negotiate (rocky, steep, etc). The Homeland Security Navistar MRAP is designed to move along America's paved roads and flat graded roads. The Humvee can cross rural bridges that the Navistar would collapse because of its weight (and end in the river). Escape from a Navistar that ended up on the bottom of a river would be difficult as people struggle to exit through the very narrow back door. And ten guys would be fighting to get through that door as water pours in. The Navistar's weakest point is its roof, which is less heavily armored that the flanks or the bottom. They don't expect anyone to throw an IED, drenched in adhesives, onto the roof or to have somebody sink an RPG into them from above (tall building or a mountain terrain environment). 

In SUMMARY
  • The Navistar is very effective in an urban environment where the zombies are armed with small caliber weapons and are not prepared to confront an armored vehicle. 
  • The Navistar's blind spots, weak(er) roof and vulnerability to IED's and rocket propelled grenades means that it can't operate in an urban environment without dismounted infantry who would have to clear an area that it would transit through.
  • The Navistar is a poor choice for a rural environment where the weight of the vehicle acts against it (ice/snow/mud/terrain). Zombies in the woods would pose a problem for the Navistar.

  1. I understand the MPG ain't too pretty good.

  2. Sounds like Janet Napolitano must have designed the vehicle herself.

    1. It's designed to run on pavement. City slicker ride. Though it should work well in hard pack desert or graded dirt roads.

  3. THE real question is when WILL they drop one through a bridge... And the really easy way to beat them is to go off road...

    1. They are designed to go where they have clear superiority in a city. Outside of a city, they'd likely just hunt people with a drone and Hellfire missiles.

  6. I am glad your son was saved. I am the designer of the Cougar and that sort of comment makes it worth the effort we put in.

    The photo of that Cougar partially demolished was after a very very large amount of explosive was detonated under the engine. No-one died - though the driver got a bloody nose.
