7.62×51mm [[wikipedia:Hollow-point bullet|hollow-point]] ammunition is a variant type of round which is optimal for use against unprotected biological targets, also employed occasionally in the [[MA5B]]. A situationally useful attribute of this ammo type is that it is unlikely to cause unwanted to damage to potentially vulnerable structures like equipment cabinets, viewports and [[starship]] hulls, making them a useful tool when taking a ship. Magazines containing this ammunition are recognizably marked with red paint.<ref>''[[Halo: Silent Storm]]'', Chapter 24</ref>
