狂妄的加特林机枪，竟然是医生制造出来保命的武器。各种类型的枪支几乎成为战场上无可替代的武器，即使哪一个军队可以选择不去购置飞机坦克等大体积的也是大杀伤力的武器装备，但是不可能不配备枪支，枪支作为战场上的常青树。也随着人类科技的进步而不断演变，成为士兵对敌时并肩作战的伙伴。而且，枪支的好坏在很大程度上决定着一场战役的成败，好的士兵再配上好的战斗武器，那就构成了堪称绝杀的组合。枪支也被人认为是取人性命的武器，这就是大名鼎鼎的加特林机枪。这种机枪威力很猛，堪称当时的战场之王，其火力让敌人防不胜防。此外，他还是一种特别的手动型多管旋转机关枪，同时也是世界范围内第一支实用化的机枪，其设计相当的经典，即使是在五十年代以后，这款加特林机枪的设计原理依旧不过时，并且还在被美国改良运用，并得到大规模的使用。看这些唬人的头号也该明白它的厉害了吧。但是令人想不到的是，就是这种爆发力惊人、杀伤力惊人的枪支，竟然是由一位医生发明制造的。这个医生叫做理查德·乔登·加特林，当时的他在战区当医生，每天都要面对这无数受伤的士兵，乃至是鲜血淋漓的尸体，而且很多都是年纪还很小的青年，真是让人惋惜不已。都说医者仁心，面对这样残忍的场面，血流成河、尸魂遍野的环境让理查德·乔登·加特林陷入了深深的悲伤，加特林心想，士兵的伤亡太重，很大程度上是因为武器的使用太不给力的原因，虽然自己只是一个医生并不能真正的去战场上杀敌。但是可以帮助他们研制一种厉害的武器保护他们。于是，他一边致力于拯救伤者，另一边开始了一个伟大的计划，他要发明制造一种枪支，能够更好的保护士兵，以此来减少士兵伤亡，于是加特林机枪开始了它的光荣之路。自从加特林机枪诞生并投入使用之后，它几乎立刻就成为了当时枪支使用者的心头爱，也成为了当时欧洲各国控制并扩张殖民地的主要武器之一，在使用中，这种枪支还不断的优化自己的性能并且提升自己的质量。改进后的加特林机枪射速最高曾达到每分钟1200发，这种破天荒的数字让不少士兵沉醉在战场扫射的射击方式中。但面对这种结果，不知道加特林医生会不会觉得遗憾，因为看起来这样的射击已经违背了他发明的初心。
