Section 1. The ration.

A ration is the allowance of food for one man for one day.

In the field there are three kinds of rations issued, as follows:

The garrison ration is intended to be issued in kind whenever possible. The approximate net weight of this ration is 4.5 pounds.

The reserve ration is the simplest efficient ration, and constitutes the reserve carried for field service. It consists of--

Ounces.
Bacon12

The field ration is the ration prescribed in orders by the commander of the field forces. It consists of the reserve ration, in whole or in part, supplemented by articles requisitioned or purchased locally or shipped from the rear.

In campaign a command carries as a part of its normal equipment the following rations:

(a) On each man: At least two days' reserve rations.
(b) In the ration section of the field train, for each man:
Two days' field and one day's reserve rations.
(c) In the supply train: Two days' field rations.

In addition to the foregoing, commanders will require each man on the march to carry the unconsumed portion of the day's ration issued the night before for the noonday meal. Reserve rations are consumed only in case of extreme necessity, when other supplies are not available. They are not to be consumed or renewed without an express order from the officer in command of the troops who is responsible for the provision of supplies, namely, the division commander or other independent-detachment commander. Every officer within the limits of his command is held responsible for the enforcement of this regulation. Reserve rations consumed must he replaced at the first Opportunity.
