Often said that urban warfare has an homeground advantage. It is probably best to not utilise Gazan males at random for first-entry. Instead, if situation permits, to try to understand the preparation of the first-entry candidates. If the males, ages ten and above, have jihadi training and/or experience, which many do, they can be helpful to identify explosive devices.
The jihadis are not able to recruit all the males into their ranks. There is a internal battle within Gaza for the hearts, minds and bodies of young males starting at age ten years old. Many families choose to protect their offspring from being recruited into the jihadi war machine. About 28,000 Gazan males are born each year. There is an effort within those first years of UNRWA schooling to prep the children towards jihadi holy war ideology. By age ten, many boys are physically and mentally capable at being absorbed for various militia tasks.
