sance for new aid stations starts as soon as the ad- vance of the attacking echelon has made suitable sites available.
b. Attack. (1) During the attack, company aid men follow by bounds in rear of leading platoons, locate and tag the wounded, and administer emer- gency treatment. Walking wounded are directed to the aid station. Locations of those unable to walk are indicated to litter bearers or are marked. Litter bearers search the area for wounded and carry non- walking wounded to the aid station. While the aid station squad is advancing behind the attack, its personnel search the area for casualties. When the number of casualties justifies it, the aid station is set up, but only necessary equipment is unpacked. When the aid station displaces, nonwalking wounded are left in groups to be picked up by collecting per- sonnel of the division medical battalion. If neces- sary, an attendant is left with the group.
(2) The headquarters section of the medical de- tachment is kept mobile as long as possible in the vicinity of the regimental command post. It main- tains contact with battalion aid stations and with the division collecting stations. Casualties occurring nearby are given treatment by the headquarters sec- tion. Equipment is unpacked and a regimental aid station set up when required.
(3) It is normal for regimental medical personnel to evacuate casualties to aid stations and for division medical personnel to collect and evacuate casualties
