Sentinel is a modular vehicle allowing rapid transformation to suit vastly different scenarios. A vehicle that is fully adept for use by local authorities and emergency services but is equipped to come to the fore in catastrophic events such as major flooding and storms and even be quickly and easily modified to cope with more demanding scenarios up to major natural disaster. This comes from the realisation that often local authorities are often left to deal with disaster, often under equipped, before central government is able to act and supply greater resources.
