If you want to know why, try reading the actual article rather than comments from fan boys here. Here is the actual reason quoted from the article:

The Israeli military has decided to ban Android phones for senior officers, on security grounds. The news was broken by Israel’s Army Radio and picked up by The Jerusalem Post. “Under the expected order, commanders from the rank of lieutenant colonel and above will be permitted to use only iPhones for official communications. The step is aimed at reducing the risk of intrusions on senior officers’ handsets, according to the report.”

Fanboys can’t handle the truth 😂. Imagine downvoting someone quoting the actual article because reality doesn’t conform to your biases.
