Abstract: A field ration packaging assembly includes a ration housing and a food tray. The ration housing includes a lid panel having at least one air exhaust vent and a wall panel having at least one intake vent. The food tray may be positioned above a heat source. The at least one air exhaust vent and at least one air intake vent may be in fluid communication such that upon activation of the heat source, air enters the ration housing through the at least one air intake vent, passes over the heat source and exits the ration housing at the at least one exhaust vent by natural convection.

Abstract: A lantern hood can be inverted from an upright, light reflecting position in which it permits the lantern to be used as a lighting device to an inverted position in which it is usable as a support for cooking utensils and permits the lantern to be used as a stove. The hood includes a lid having apertures formed therethrough which can be opened when the hood is used as a cooker and closed when the hood is used as a reflector. The hood also preferably includes a cooking cylinder shaped so as to support standard sized camping utensils when the hood is inverted, and springs for pulling the globe of the lantern into contact with the inverted hood to channel the heat from the lantern through the cooking cylinder, thereby enhancing the hood's operation as a cooker.

Abstract: An apparatus for providing a warm environment within a cold environment, comprising a table having a surface member, heating means disposed beneath the surface member, an insulating layer disposed between the surface member and the heating means, and a skirt member secured to the surface member and depending therefrom, defining the warm environment, whereby persons sitting at the table are partially enveloped by the skirt and thereby kept comfortably warm, despite substantially cooler temperatures in the cold environment.
