监视侦查是一种策略性的手段。把一个单位放在某个位置，从战略意义上你可以监视这个区域。比如BB地图你可以把单位驻扎在地图周边房子里，你就会获知对手是否并且何时向该分矿区域扩展。

Another example is placing a cheap unit or a submarine in the water on Infinity Isle where potential harassment-moves such as Cryos or TwinFrogs are coming in from. That way you will know about it when it's coming and buy time to prepare.

另一个例子，像在II地图，把一个廉价的单位或者潜艇放在可能会有冷冻或者双刃骚扰经过的水域，你就活知道对方什么时候来骚扰，这也就相当于花钱买了让你准备的时间。

To formulate it more clearly:

Through aim-oriented scouting you check if something already happened such as a tech-up, an expansion, production of a type of units.

Through monitoring scouting you supervise when something you might have predicted eventually happens such as harassment coming in, or a Refinery goes up which you plan to harass instantly.

更系统的说明的话：
通过目的侦察你是确认某些已经发生的事情，比如升级科技，拓展，或者出了某种类型的单位。
通过监视侦查你是监视被预言的事情何时最终发生，比如骚扰，或者是立即骚扰对方。

Logically, you can use an originally aim-oriented scout and put it in a location it monitors the area, given that the unit didn't die in the process of the first scouting task. On the other hand you can use a monitoring scout to check something. The two forms of scouting are transformable.

逻辑上而言，你一开始可以使用侦察单位进行目的侦查，然后把它放在某个位置来监视某个区域，别让它在第一次侦察任务中损失。另一方面你也可以用监视侦查的单位去确认某些信息。二者之间可以相互转换。

Try missing sneaky flanking

试试占据侧翼

In my eyes players underrate the value and benefit that arise from intelligence. It's hard to come out ahead from a fight through micro. Through scouting you can compose your army better and with that make your army stronger while not bigger resulting in you having advantage before a fight even starts.

在我看来玩家低估了情报所能带来的价值和利益，在一场战斗中很难通过微操获得优势，通过侦查你可以让你的部队组成更加合理，更加有战斗力，而在战斗开始前你就占有了优势。

Observation outposts are also highly underrated!
观哨站总是被忽视！

The lines point to expansions you can monitor and the elipse is where most players park their armies.

你可以监视线段指向扩展的位置，椭圆类是大多数玩家布置他们主力部队的地方。

As scouting is so important and information is so valuable, the mechanics of anti-scouting are a separate story and a layer of skill in RA3.

侦查如此之重要，信息如此有价值，而反侦查的技巧又是另一个单独的模块，另一个层面的Ra3技巧。

4. Map-control地图控制

Map-control means controlling certain areas of the map in a way you make it harder for your opponent to pass that area. Consequently, wherever units or turrets of yours are the area is under your control - control meaning that your opponent will have to invest both units and time to pass through the area.

地图控制指的是通过控制地图的某个区域是对手更难得通过这个区域。因此，你的单位和炮塔占据的地点势力控制的区域，控制指的是你的对手只有投入兵力和时间才能通过此区域。

In the very beginning of a game there will usually be a run for the garrisons and the Oil Derricks. Whoever gets there first wins that race in most of the cases. The winner of that race is depending on who

timed build and unit order better as well as who supported the garrison occupants - respectively the Engineer - better.
游戏一开始一般会有一个可供驻军的地方和一个油井。多数情况下谁先到达谁就会在这场小冲突中获胜。谁是获胜者取决于建造时间和兵种顺序谁更好以及谁先进驻房子，还有双方的工程师。
