knowing they may never return是现在分词短语.分词短语可以作时间、原因、条件、方式伴随状语.例如：
 
Learning of the accident, he was from home on business. 听到这次事故的时候,他在外地出差.（时间状语,= when he learned of the accident） 
Knowing they may never return, they are ready to part their hometown and never meet it again 因为知道他们永远也不给会回来,他们做好了与家乡永别的准备.（原因状语, = Since they know they may never return）
 
此处是伴随方式状语,表示“与此同时,知道他们永远也不会回来”可以改写为并列谓语People in the military leave their hometown to defend their country and know they may never return.
 
aware是形容词,也可以作伴随状语,但是介词of后不能跟宾语从句,需要把从句they may never return改为动名词复合结构 their/them never returning（见昨天的回答）,即——
 
People in the military leave their hometown to defend their country aware of them/their never returning.

knowing they may never return做的是伴随状语。
你的改写是不对的：如果这样的话，句子会有leave 和aware of 两个谓语动词。你可以在aware of前加and。
谢谢！写错了，是being aware of they may never return语法上是对的。因为know直接做伴随状语话，就直接用knowing,而be aware of 系...

在军事的人离开他们的家乡来保卫自己的国家知道他们可能永远不会回来。 “知道他们可能永远不会回来” 没问题啊

“knowing they may never return”做主语补足语，是句中“People”的补充动作及修辞词，不可以用aware of，有个词组是“be aware of"”aware of“ 不可以单独做谓语成分当作动词来用的。
