一来二去的这一番折腾，三四个小时过去了，士兵伤亡无数、坦克也折损不少，但进攻毫无进展，并且连突破的希望都看不到，部队只能暂时退下来，紧急请求战术指导。更多小说ltxsba.com
德州，国军前敌总指挥部。
蒋浩然手持电文微微颤抖，口里喃喃惨呼道：“龙牙，是龙牙，他们居然是修筑了一条龙牙防线？”
“龙牙？龙牙是什么东西，很厉害吗？”林珑嘴快，急问道。
所谓的的“龙牙”其实就是反坦克锥，是用混泥土铸造的一种三棱锥，类似金字塔，大概是半米高。
在坦克为王的战争年代里，反坦克的武器也是层出不出。为了对付在陆地上凶猛无比的钢甲铁流，各国也是费尽了脑筋，不仅造出了很多高科技反坦克武器，而且还有很多简陋且造价低廉的反坦克武器。
最有名的就是捷克的“捷克刺猬”和德国的“龙牙”，前者是角铁焊制的一种以L或H型钢交叉而成反坦克障碍物，成本较高。
而德军发明的“龙牙”则是用混泥土浇筑而成的三棱锥，它被布置于作战区，形似金字塔，约半米高，构造非常的简单，成本也是极其低廉，也正因为如此，在二战时期它被大面积的用于地面战争，对于坦克、装甲车来说简直是噩梦一般地存在。
龙牙反坦克锥有三个平面，当坦克想要通过爬坡的方法来翻越反坦克堆时，会因为两个履带都在三角锥上而没有着力点被卡在上面，就像是被千斤顶给顶起一般，就算是坦克能找到着力点加速，也不可能摆脱反坦克锥的支撑。
因为在坦克的带动下，反坦克锥每滚动一次，就会把一个棱角翻上来，那么坦克终究还是会被卡住，不爆破，坦克就根本就无法动弹。
德军第一次使用龙牙是在诺曼底登陆战中，海滩上密密麻麻的的三棱锥，给盟军带来了极大的伤亡，所以德国人将其称之为“龙牙”，寓意为牢不可破的防线。
其实，在现代化的战争中，这种武器早已过时并退出历史的舞台，因为现在讲究的是精确打击，二战中这种大规模的战争场面不再容易看到，所以反坦克锥也就没了用武之地。
反坦克锥之所以能够成为二战后期的重要武器，那是因为在这个特殊的年代里，信息相对比较落后，两国间的战争多是大规模的军事对抗，战争中无法准确地判断出敌方的军事态势，所以大多数的军事行动都是高消耗的盲目推进。
多以地面装甲部队开展战争，国与国之间打的是高消耗战，所以这就使得反坦克锥有了大展身手的机会，虽不能直接对坦克造成杀伤。不过却能给敌人带来很大的麻烦，所以，相比较其它反坦克武器来说，它更实用，也就成了制约坦克的最佳武器了。首发..
可惜蒋浩然的大脑中存储的都是些高科技武器，对这些“土制品”根本没有任何记录，而他对龙牙的认知完全是基于前世对军事的爱好，或许在某本书里或是某场电影里看到过，潜藏在记忆深处，直到见到或是听到了实物，这才“恍然大悟”。
