Fpv drones (both grenade dropping and rpg ramming types) are more effective and kind of easy to produce in sweatshops. It is prone to jamming but if this issue is solved as it seems it is kind of solved by antenna configuration in Ukraine-Russia conflict there are many many video footage examples against tanks and infantry soldiers alike. For atgm and rpg you need to get close to the target and have direct line of sight and after the attack have a plan to escape the area. For fpv drones it is indirect fire and the source location cannot be determined easily.
Hamas fighters can produce fpv drones and attach rpg or grenades on them in Egypt. Even if they can't transfer the fpv drones inside Gaza they can still make successful attacks on israeli soldiers or armor stationed on Rafah crossing by fpv drones controlling the drones from Sinai Peninsula in Egypt. Good fpv attack drones have about 15km range. Hamas should claim the drones are operated from Gaza to not to drag Egypt into the conflict. Hamas can open fake transmitters at the same time in Gaza too as if they are commanding the drones from there while drones are controlled from Sinai.
