Model 1 is intended for nontactical use by the Government in transporting personnel and cargo on local streets and roads and for on-station usage over improved roads. Model 2 and model 3 are intended for nontactical use only within the confines of military installations, over improved roads, with limited and low speed traffic where licensing of vehicles for roadway use would not otherwise be required. The use of model 2 and model 3 on the roads at large military installations with heavy traffic is not intended.
