Are all the missions in Delta Force Task Force Dagger and Black Hawk Down real?

[black hawk]

What I want to know is that, are all the missions in Delta Force Task Force Dagger real? I can't believe that most of the missions could be completed by a single soldier or just 3 soldiers if it were real. For example, in Operation Harakat part1 and part 2, how can just one soldier do a raid in a hotel. In part 2, I was told that Alpha team would give me sniper cover form an orbiting black hawk but there was none. In some missions, the commander says Cobra 33 team will engage...... but there is no team except me. The same question goes for Black Hawk Down because the missions seem a bit different from the consequences shown in the film. One last thing, does anybody know why the friendlies in one of the missions in tfd don't even have a gun, while they have to eliminate a whole convoy?
