3.It is relatively unusual for Israeli soldiers to be injured in such exchanges.

It is+adj.+of sb. +to do sth 与It is +adj.+for sb.+to do sth的区别。

It is+adj.+of sb. +to do sth中的adj.跟sb.有关,
这个adj.是用来形容sb.的,
表示某人这么做真是太adj.了．

你会发现在这个句型中你把sb.和adj.提出来可以造个句sb. is(are) adj.
如It‘s very kind of you to help me.
把里面的sb.和adj.提出来可以发现you are kind是说得通的.

而It is +adj.+for sb.+to do sth表示做某事对某人来说很adj.
这里的adj.是do sth.的属性
里面的sb.跟adj.没有直接联系
如It‘s difficult for you to deal with the problem.
