A young soldier on the night of 7/10 warned that Hamas was going to carry out a raid but no one commented
Almost two years had passed since 7/10, but that night in the intelligence camp of the Gaza Division, an interesting thing happened that had not been published so far when a soldier named R. who is not an officer looked at the signs and was sure that the complacency was wrong and expressed grave concern, but the commander was not impressed and the division commander who was at the base did not even bother to get to the camp".
A BAM investigation tried to check R's alerts and did not reach unequivocal conclusions on his version, but senior IDF officials were convinced of his credibility and seriousness
