We see in TV via regular meeting, general meeting sends a few people to stand sentry to also can say outside base on army is to stand sentry. These people are called piquet to be in charge of technically standing sentry namely, prevent the camping ground that has enemy him infiltrate namely, they are protecting the security of whole army, the job is very main. So if fail to be opposite,go up on battlefield catchword, can piquet shoot directly? Veteran will tell you the answer! Actually also cent plants piquet, but they have a common characteristic to execute the mission strictly according to discipline then. Guard also has countersign, also answered sb's question only of course countersign ability is close to chirp, in the process that general piquet is standing sentry or patrols, encounter the person with very doubtful behavior can enquire countersign of the other side. It is oneself army medium person is stood by also can be asked to answer countersign, because this is army medium discipline. If in this moment you do not have the countersign on the answer to perhaps say you forgot, sequential nature is very then serious. Each legionary now piquet is two people commonly, among them a person hold gun, another person is in charge of bullet this is to prevent accidental injury. And the cartridge of before a few hair that holding inside the gun is to be played for nothing, and this practice is to warn a suspect completely. When piquet is enquiring your countersign if you do not answer to come up, he can shoot, but this is a sky only play use those who warn you, if the warning does not have action, so piquet has authority to have fire to you. Be in before in warlike time, a lot of people are taking bad purpose to come, if one have neglect,perhaps let the enemy enter barback to may cause very serious consequence then. Be about to make a prompt decision to piquet so, if the warning is not effective,that disconnects with respect to meeting fruit gun. Now although we are in peaceful time, but the position that piquet also is need height concentration, if the other side does not answer,just go up countersign also won't shoot directly normally. We have jurisprudence to be able to be relied on now, the life of people also is very precious respectable.
