    I notice that the `` tags are empty - there is no Korean text provided between them to translate. The surrounding context shows some bash script code, but that appears to be outside the translation section and is already in English. Could you please provide the Korean text you'd like me to translate?

    ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
    **[KILL-9 Broadcasting]**
    
    Soldiers, listen up.
    
    The draft of Death Spring Batch 6 has just been completed.
    
    Months of redesign operations are complete.
    All limitations of the existing course have been reanalyzed,
    and all improvements of Spring Batch 6 have been incorporated.
    
    [Operation Schedule]
    - At earliest: Within a week
    - At latest: December 31st
    
    The course content will be completely updated.
    
    There are many changes. Official documentation won't be enough to keep up. Prepare yourselves, Kill-9 Squad.
    
    ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
    [Major Changes]
    
    ✅ Full Spring Batch 6 Support
       └─ New APIs, new patterns, new tactics
    
    ✅ Complete redesign of existing course structure
       └─ All limitations pointed out by soldiers improved
    
    ✅ Rewritten with practical code focus
       └─ Clearer, more practical, more dangerous
    
    ✅ Enhanced KILL-9 Tactical Manual
       └─ Chapter 6 operational tactics greatly expanded
    
    Of course, improvements will continue.
    But at this moment, we have evolved one step further.
    
    ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
    🚨 [IMPORTANT NOTICE] 🚨
    
    [PRICE POLICY ADJUSTMENT - 2026]
    
    Starting in 2026, KILL-9 Squad will implement
    a new operational policy.
    
    [2026.01.01 00:00 - New Standards Applied]**
    
    Current pricing policy (29700)
    ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 2025.12.31 23:59:59
    
    New pricing policy (88000... approx)
    ░░░░░░░░░░░░░░░ 2026.01.01 00:00:00(approx)
    
    We've already recruited 666 members. The goal has been achieved.
    From now on, only the real ones who are serious about learning.
    We want to operate missions with only the elite.
    
    
    [Existing Squad Members]
    Everything remains the same for soldiers who have already enlisted.
    All updated tactics will be provided.
    
    
    [Background for Policy Change]
    Cannot be disclosed at this time.
    But there is definitely a reason.
    
    - February or March 2025
    - Everything will become clear then
    
    ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
    [KILL-9 FINAL MESSAGE]
    
    Soldiers,
    
    The battlefield has evolved.
    We have evolved too.
    
    **From now on, KILL-9 Squad operates with only the elite.**
    
    The era of Spring Batch 6 is coming.
    Only the prepared will survive.
