The V shaped hulls of the MRAP give it a higher center of gravity and the weight of the MRAP can cause the poorly built or maintained roads in rural Iraq or Afghanistan to collapse.

For example, local materials such as coconut coir and rice hulls have made it possible to adapt substrate systems that would normally have required know how and technically demanding materials (e.g. rockwool) not widely available in Article 5(1) countries.

Shipworms are responsible for the loss of very many wooden hulls, but Christian Huitema in the original draft noted that the animal only survives in relatively clean and unpolluted water its recent comeback in several Northern American harbors is a testimony to their newly retrieved cleanliness.
