“The Shield That Defied Bullets 🛡️”

[0:02]It was considered the strongest shield in history, even a spear that pierced iron armor couldn't scratch it. But the enemy noticed a small hole in the shield and immediately thrust his spear through it. Unaware that the hole was a trap deliberately designed to ensnare the enemy. When the spears had no effect, the commander changed his strategy and signaled his soldiers to raise their guns and fire. As soon as the shield bearers saw this, they immediately strengthened their defenses. The soldiers pulled the triggers and bullets flew in all directions, but something surprising happened. Every bullet hit the shield and bounced back because the shield was so intelligently designed. The outer layer was made of flexible rings and the inner layer was lined with copper. Even the most powerful bullets could not penetrate it. Soon, the enemy's bullets ran out. As they began to reload, the soldiers with the shields seized their opportunity. They formed a strong line and advancing with full force launched a fierce counter attack. Now tell me, which country's shield is this?
