Egypt unveiled S-300 system

I'd be happy to help translate this Persian news headline to English. Here's the translation:

Egypt's Unveiling of S-300 System Concerned the Zionist Regime

However, I notice you mentioned a specific structure with markers (▸ lead paragraph, • bullet lines,. coverage-difference paragraph), but the text provided only contains a headline. Could you please share the complete news summary including the lead paragraph and bullet points? That way I can maintain the exact structure you've requested.
