Just a quick one re what actually is used on the ground. Seeing many images of the fighting and most breaches into compounds seem to be done with C4 blocks on wood. What about clearing rooms, again just standard Hand Grenades chucked in or does the UK have a âdefensiveâ grenade (Blast with little shrapnel) or just the bog standard HE Offensive type? If so does anyone know if any field made type of âbunker Busterâ is used? Rhodesian sanctions and all that, the toms then used to fill plastic boxes (the containers from their grenades) with C4 and stick a det from a hand grenade into it. Made a fierce blast weapon that took out, well bunkers and rooms. Disabling the occupants permanently without harm to the troops or civilians close to the blast. Or is this against the Geneva Convention nowdays?
