An assembly, and an associated methodology, for providing personnel with training and other instruction. A workstation is configured at a support structure, such as a trailer part of a motor vehicle. The local network, once configured, is transported to a location in proximity to the personnel that are to undergo training. A wireless connection, such as a satellite communication link, is formed between the local network and a centralized training host. Training modules are downloadable, by way of the wireless communication link, to the local network, and personnel receive training through use of the workstations, in conjunction with instructor-led instruction, by way of the workstations of the local network.
