The Ambiguous Handover Order

1. 'until the armourer has cleared ... AND the range officer has inspected the butts' Is this one composite condition (movement resumes only when both are complete) or two separate gates (movement resumes once the armourer is done)? The butts cannot be inspected before Friday, so one reading closes Range B for two more days and the other reopens it this evening. Highest risk: the butts are where rounds land. After a reported fault, an uninspected butt is exactly where a person is standing when the next round lands.

2. 'unless the range officer confirms the fault is cosmetic' The exception is grammatically attached to the reassignment sentence, but is plainly meant to govern the suspension. Read literally, a cosmetic confirmation cancels the reassignment while leaving the suspension in force - incoherent. It also leaves open whether a telephone statement counts as 'confirms', when the purpose of the clause is a recorded check.

3. 'No live firing on Range C either' 'Either' borrows its meaning from the previous sentence, which banned movement and firing. It is unclear whether C is closed to movement too, or only to firing.

Ranking rule: the reading that is hardest to undo if wrong governs. A cancelled exercise costs a day. A round into an uninspected butt costs a life. So reading 1 goes restrictive; reading 3 goes permissive, because stopping movement on C is reversible and stopping firing is not.

• 16:40 Keep the fourteen cadets at the gate under a named NCO. They do not move to Range B on the strength of a telephone call.
• 16:41 Declare Range B closed to movement and firing until the written butt inspection exists. The armourer's clearance satisfies one limb only; the composite reading is the safe one.
• 16:42 Ask the range officer for written confirmation by the agreed method (signal log or email) and record in the duty log that you asked, and when.
• 16:45 Ban all firing on Range C; permit movement on C. The narrow reading is defensible because it is the reversible one.
• 16:50 Re-task the cadets. The drill hall is the band's from 17:00, so use the classroom and vehicle park: weapons handling drills and kit layout, not range work.
• 16:58 Brief the orderly officer now and the duty sergeant at 18:00; enter the decision, the times and the reasons in the log.

Principle: when an order is ambiguous and the consequence is irreversible, take the restrictive reading and resolve the ambiguity in writing. Never resolve it by assuming good news.

'Range B is closed to all movement and all firing until both (1) the armourer's clearance is entered in the armoury log and (2) the range officer's butt inspection is recorded in writing. A verbal statement satisfies neither condition. Fourteen cadets are re-tasked to the classroom. No firing on Range C; movement on Range C is permitted.'

Why this works: each ambiguity is closed explicitly. Both conditions are named, their form of evidence is specified, the verbal loophole is shut, the exception is deleted and the Range C rule is split into firing (banned) and movement (allowed). Nothing is left to be inferred from context.
