I discovered a recommendation to make you a field agent.

我发现了一封推荐你做探员的推荐信。

I suppose whether he's fit to be a field agent.

Locusts thrive in conflict zones and under-resourced regions; field agents may well stay home if they risk being shot at, or if there is insufficient power to run their equipment.

蝗虫在冲突地区和资源匮乏的地区肆虐；如果外勤人员冒着被枪击的危险，或者没有足够的电力来运行他们的设备， 他们很可能会呆在家里。
