关于任务编辑的文字显示

分贝多

ARMA新人，请编辑器老手帮忙。
我编辑了一个任务有3方，想让每方在任务开头都能看到不同的各自的任务简报，请问如何写才能让特定的一方看到只属于其自己的简报呢？
我是这样写的，在任务里3方都能看到：
"Quick briefing:" hintC ["Due to the bad weather you were just crash on the enemis' island somewhere SE-E of airfield,all other crew men was dead.","You sent a message to the HQ,HQ said they will send a special team to meet you at north of airfield,then the communtion was down.","The enemy must search for you too.","Your task is hide and move to north,try to meet the secure team."]
