Surface transportation allows for the smooth functioning of society and the exchange of goods and services that help fuel a nation's economy. Furthermore, the transportation sector is often not only the target of terrorist attacks, but can serve as a terrorist weapon or delivery mechanism. This explains why roughly one-third of all terrorists attack worldwide target surface transportation systems, with the weapon of choice usually being explosives. By means of an integrated security approach, Fortitude has a set strategy to protect surface transportation against terrorism and crime.
