Regarding Infantry soldiers riding on a Utility Helicopter (Blackhawk). The helicopter would place "skids" down (wheels) for about 10-20 seconds or long enough for all 6-8 Infantry soldiers on board to get out and lay in teh prone around the helicopter and then take off to go loiter some place safe or to complete a follow-on mission. The Infantry would then form a 360 degree perimeter as Coop stated the USMC did at Mashtuur City recently. The extraction point would actually be in a different location but if they knew it was uncontested they could be extracted from the same LZ/PZ*.
LZ/PZ - Landing Zone/Pick-up Zone.
