Marines with Bulk Fuel Company B, 6th Engineer Support Battalion, set up a fuel pump during a training exercise here, July 17. Bulk fuel Marines practiced setting up fuel points across long distances in order to mimic real-life scenarios. Much of the work required Marines to rely on group strength as opposed to machines to assemble the amphibious assault fuel systems. - Marines with Bulk Fuel Company B, 6th Engineer Support Battalion, set up a fuel pump during a training exercise here, July 17.
