You have no idea. I WISH we could have controlled what they wanted us to do when we had them with us.
If they were embedded with you for the day, expect to go DIRECTLY towards anything that explodes or shoots.
Normally, a unit stays within their sector, but when you have a journalist in your squad, it's a bit different.
I was unlucky enough to have this CNN reporter with our unit at one point:
Tripoli Falls to The Freedom Fighters
So, our mission was to hand out supplies to a local school (normally, this was done by the FSB troops, but our commander wanted to look good on the news, and since I was a gunner in the command convoy, I got to go with).
We arrived at the school and handed out stuff for about an hour. Her camera-man took about 5 minutes of footage, none with her. She talked with our commander and took photos for a bit, then waited in the HMMWV. After the first hour, there was a huge explosion and smoke-plume off in the distance. It was outside our AO so we kept handing stuff out. That is, until the reporter DEMANDED that we take her there (despite the reports that there was a conflict between insurgents and IA and Coalition forces). At first, we told her no, because we had our commander with us, and we had the supplies to hand out, But after she called the brigade commander, we were ordered to go. So, we split our patrol up into 2 groups (one to continue handing the supplies out), and the other took her to see the fighting. Luckily, I got to stay with the group handing out the supplies. When the other group returned to base (roughly 5 hours after we split up, and 3 full hours beyond their scheduled return time), our commander stormed into his office and the reporter left to go send her segment in. I don't remember what her segment ended up being about (didn't really care), but I know that a lot of soldiers were pissed about it and there was nothing that could be done.
The media reports what they want. The best our government was able to do, was to force censor any pictures or videos that showed the deaths of soldiers until their immediate family had been notified. Which again, is STILL not always the case (I've heard more than a few stories of reporters who got their stories to the US before the "media blackout" was started and loved ones heard about the deaths of their sons, daughters, or husbands from the nightly news shortly before they were informed by the military).
If we can't even stop them from reporting long enough to properly alert the family of fallen soldiers of their loss, then there is NO WAY we could censor them about anything.
