Please be advised that there was a clerical error in the weapon and equipment regulations within the published event guidelines. We have made the following correction and addition. This update primarily includes a relaxation of requirements and an important addition for safety management.

1. [U8, U10, U12 Categories] Amendment to Mask Regulation
   Masks: 350N can be used (1600N recommended).
2. [Important Addition] Mask Retention System (Double Band Requirement)
   The following double band requirement has been added to “13. Weapon and Equipment Regulations” under the common mandatory items for all categories (immediately following the paragraph regarding the 800N under-plastron).

Mask Retention System (Double Band Requirement):
For safety management, all categories (U8–U17, Veteran, PV, and Para) are required to wear masks equipped with a “Double Band (FIE-compliant retention system)” that secures the back of the head doubly. Traditional single-band masks or masks with loose straps due to deteriorated elastic will not be permitted.
