bridge or 2 No 12 bridges. It can drop off a load of bridges independently, but it cannot recover them. This is no major limitation because bridges are usually left or destroyed in place. No 10 Bridge The No 10 bridge is a scissor type bridge that can be quickly launched and deployed by TITAN however it is not very long and can not cross water itself. No 11 Bridge The No 11 bridge is an 'over and up' bridge. It can be launched very quickly (adopt 15 minutes) and is made up from 2 ramp sections of BR90. No 12 Bridge The No 12 Bridge is 'up and over' bridge. It is the only CSB that does not use the BR90 components. Two can be carried in by 1 TITAN (AVLB), but are launched and recovered separately. Combination Bridging An attachment for the No 10 bridge called a trestle can be used to enable greater spans to be achieved. Using a trestle multiple bridges can be used in combination. This has been proven popular in Afghanistan when rivers are often very wide however since 2005 heavier bridges have been used. Other Bridging Systems Medium Girder Over Bridge The Medium Girder Over Bridge provides an over bridging capability. The bridge set is transported on 1 DROPS pallet and 1 Field Section (Fld Sect) can build it. It is used to reinforce current bridges to allow heavier traffic. It can also be used as a bridge on its own but it does require extensive foundations. Heavy Girder Over Bridge The Heavy Girder Over Bridge (HGOB) provides a lower profile allowing easier crossing for heavy transporters and tankers on line of communication routes. The bridge is transported on 1 DROPS pallet of a 14 tonne truck. A Royal Engineers Section and a crane is used to construct the bridge. The bridge can be constructed by hand but the components are extremely heavy. Like the Medium Girder Over Bridge it is used to reinforce current bridges to allow heavier traffic also like the Medium Girder Over Bridge it can also be used as a bridge on its own but it does require extensive foundations. M3 Amphibious Bridging The M3 Amphibious Rigs are vehicles operated by a 3-man crew. The M3 Rigs can drive into the water, open up and join together to create a bridge of varying length. A 100m bridge can be
