The Ranger is a unit in They AreBillions. The Ranger is built in Soldiers Center.
游侠是亿万僵尸中的单位，可由军营训练出来
It is a cheap, quick unit with a bow andarrows as a weapon. According to the in-game description this unit is best usedto scout and hunt down small groups of infected since its weapon is silent anddoes not attract many infected.
她是一种用弓箭攻击的廉价、快速的单位。根据游戏内描述，由于游侠的弓箭不会造成噪音（僵尸只会被噪音吸引），她们最适合于侦查以及消灭小股尸群。
Because of their low cost and maintenance,they can easily be built in masses. After the early game, however, they areoften replaced with Soldiers and Snipersdue to their lack of overall firepower.
由于造价和维护费低廉，玩家可以很容易地训练出大批游侠。但是在游戏初期结束后，游侠往往会因为综合火力不足而被士兵和狙击手所取代。
They are really useful when near a Village of Doom, because they don't triggeradditional zombie waves and don't attract many nearby zombies when attackingunless in large groups.
游侠在靠近厄运小屋（小王）时十分有用，因为她们不会造成暴动或者引来尸潮，除非游侠数量过多（按贴吧大佬们说的单位时间噪音不为0了）

The Soldier is a unit in They AreBillions. The Soldier is built in Soldiers Center.
士兵是亿万僵尸里的单位，可由军营训练出来。
Soldiers are versatile units thatprimarily act as hardy frontline infantry, having more health than Rangersand more armor than both Rangers and Snipers.
士兵是用途广泛的单位，主要充当着坚韧的前线战斗者，拥有多于游侠的生命值，以及多于游侠和狙击手两者的护甲值（减伤）。
Their submachine gun is powerful enoughto stop small groups of infected with relative ease, but the noisethey generate can attract nearby infected if the player is not careful,possibly triggering Villages of Doom.
他们的轻机枪有足够的能力去相对轻松地解决较少的僵尸，但是玩家走神的话他们可能会引发暴动或者招惹到老王（轻机枪单位噪音比较大）。
The Soldier acts as a middle groundbetween the Ranger and Sniper in terms of firepower, having a faster firingrate than both. This allows them to be better at defending against normalinfected and reasonably good against Infected Venoms because they have resistanceagainst venom (50%), making them effective defensive units, especially whenplaced in towers to extend their range.
士兵的火力在游侠与狙击手之间，但射速超过两者。这一优势使得他擅长防御普通僵尸以及五娃（50%的毒抗），让他成为聚居地坚实的防御力量，尤其是上塔扩程之后更是威力倍增。

A unique bonus that this unit has isthat it acquires more experience of the zombies than the other units, allowingit to reach the veteran degree faster. Another extra bonus of Soldiers is thatthey regenerate their health at the rate of 5 HP/sec, making them usable fasteragain, after taking heavy damage.
士兵的独有特性是获得经验的速度比其他单位高，这使得士兵成为老兵的速度也随之提高。此外士兵能以5点/秒的速度回复生命，这让士兵们即使遭受重创也能在短时间修整后重新投入战斗。
Squads of soldiers can be adequate forclearing the map of normal infected, but caution must be taken when they willbe attacked by Infected Harpies.
小队士兵可以有效剿灭正常僵尸群，但是请注意鹰身女妖的威胁。（这段话结尾的“infected Harpies”即指鹰身女妖）

解析：（这段翻译打过来起码删掉了五次“铁头”换上“士兵”），铁头的，咳咳，不是，士兵的语音字数很少，言简意赅，言语中透露着对指挥官的尊敬、对命令的遵从以及对消灭僵尸的高昂热情，一听就知道是训练有素且久经沙场的战士。大家在看到士兵插图里厚厚的盔甲时就知道他的面板肯定至少防御力肯定是很高的。士兵在生存模式里的用途一般是中期清图，充当小型机动救火队或者在防线出现破口时顶上缺口当人型堡垒，用途一般，但是在战役模式中由于满科技铁头面板暴增，能打能扛射程远，人一多秒天秒地，反而成为了保卫聚居地和清图的主力军（铁头爹的名号可不是白叫的），相比游侠，士兵自然给人一种“聚居地保卫者”“钢铁防线”的印象。
还不谢过铁头爹？

No.3狙击手（sniper）
名字来源：snipe是一种敏捷的小鸟——沙锥鸟, 十分警觉, 在驻印英军中, 猎取snipe是一种高难度的竞技性的运动, 不但枪法要好而且必须不惊动猎物，因此长于此道的人被称为sniper，后来狙击手便沿用称为sniper 。

"Your sniper, at your service."您的狙击手为您效劳
"Nothing better than to put some bullets through somebrains."没有什么比爆头更好的事了
