在真正的历史当中打仗的时候，如果其中一方高挂免战牌，那敌人也不可能就因此选择不进攻。想想看作为进攻的一方，怎么可能会因为防守方的意愿来改变自己的战略呢？打仗本身就不是一件儿戏，如果随随便便就改变了自己的战略意图，那不就是在拿自己士兵的生命开玩笑吗？
其实很多人之所以会了解免战牌，那是因为在很多的影视作品当中我们会看到这样的情节。双方交战之时，但其中的一方比较的弱小，或者是没有做好相应准备之时，就会高战免战牌，此时另外的一方就不会继续在城外死磕。当然我个人觉得这种说法其实就是一种戏说，或者说是为了增加影视作品还有小说清洁的情趣才出现的一种说法。最起码在真正的历史当中，关于免站牌的记载是少之又少，甚至可以说是没有的。
当然在最初期的时候，双方如果要交战，确实是要约好一个时间和地点的，到了约好的时间和地点之后，双方的兵马就在该地区拉开架势，然后面对面的干一场。若双方觉得两边的兵马数量是均等的，算得上是势均力敌，那么就会直接进行大决战，因为这样战争的损耗就会更加的小一些，对于双方来说都是非常有好处的，在最初的时候，这算得上是君子之战。
不过后来战争也是慢慢的演变成了一种心里交锋，特别是到了战国时期，这种所谓的君子之战根本就不存在了，上方兵马在交战之时玩的就是心理战，玩的就是一些阴谋诡计，可能就不存在有提前约架的说法。而在这之后打仗，其实就是要靠谋略了，就算你高挂免战牌，那么敌人只要取得了巨大的优势，同样会摧枯拉朽的去进攻你。
不是的，需要看进攻方将领 的指挥。
如果将领觉得自己的军队有能力深度进攻，直接拿下敌方首领，那肯定是乘胜追击的；如果进攻方也刚好是体力不支，那么会顺势休战。
大部分都是不进攻的，但是这个免战牌也不是挂出来就有用的，这是打仗的时候的不文明规定，但是也有不遵守这个的，搞偷袭不择手段的也有。
不，他们还是会进攻的，免战牌挂上后，说明军队此时不愿交战，只是个预告。但是敌军还是会找人把免战牌砍了，继续进攻。
