In a promotional video posted on Al-Qassam Brigades on Telegram, teen participants in Hamas's "Pioneers of Liberation" summer camp wear Hamas military fatigues and simulate launching anti-tank missiles at an Israeli bus and tank, infiltrating an IDF outpost, and liberating the Al-Aqsa Mosque, among other simulated military training activities. The video was posted on June 25, 2021, ahead of the opening of Hamas's "Pioneers of Liberation" 2021 summer camp the next day.
Caption: "This is how they had trained and executed with precision. Stay tuned for Al-Qassam's simulator system at the Pioneers of Liberation summer camps."
