ImpSec Duty Personnel Ration-Only Rule

The ImpSec Duty Personnel Ration-Only Rule is a security precaution requiring personnel on duty to eat only rations issued by ImpSec. Its purpose is to reduce the risk of attacks using drugs or poisons introduced through food. A brief exchange over Martin Kosti’s lunch sets that institutional caution against the trust involved in accepting food prepared by family.

Purpose and Scope

The rule applies to ImpSec personnel while on duty and excludes food from outside the agency’s issued rations. Its rationale is practical rather than dietary: food brought in from elsewhere could provide a route for ingestible drugs or poisons. The restriction therefore turns an ordinary meal into a matter of operational security.

The Rule in Practice

Martin Kosti’s mother sends him lunch every day, mostly prepared by her. When a brother reaches for one of the sandwiches, Kosti bats the hand away and insists that the food is his. Miles Vorkosigan recognizes the apparent breach of the ration rule but does not intervene. He is no longer serving as an ImpSec officer responsible for enforcing its regulations, and regards strict enforcement in this family setting as unreasonable. The scene does not cancel or formally revise the rule; it shows its practical limit in a moment where institutional suspicion meets personal trust.
