c. Litter bearers or motor ambulances of the col- lecting company evacuate casualties from aid sta- tions to division collecting stations. These collecting stations are usually located between 1,200 and 3,000 yards in rear of the front line. At the collecting sta- tion, casualties are again sorted.
d. Casualties requiring further evacuation are transported by motor ambulance from the division collecting stations to the division clearing station, some 4 to 7 miles in rear of the front line. In this clearing station, sorting again occurs. Casualties re- quiring further evacuation from the division area are turned over to a medical unit of a higher echelon for movement to evacuation hospitals. Ordinarily an ambulance unit of the army medical service renders this evacuation service.
46. MEDICAL SERVICE IN CAMP OR BIVOUAC. In camp or bivouac, the headquarters section of the detachment, or the entire detachment functioning as a unit, may establish a dispensary which oper- ates for the entire regiment. In certain cases, separ- ate battalion dispensaries may be set up within each battalion area. The regimental commander, on re- commendation of the regimental surgeon, designates the methods to be used and the hour of sick call. Sick call usually is held immediately after the camp or bivouac is established. Arrangements are made to have men requiring evacuation removed from the regiment by divisional medical units. Prophylactic stations are set up and operated at each dispensary.
