Generals:Para Drop
From Command and Conquer Wiki
"Sigh... You have trained to many men general they will all be crushed underneath my threads."
- Kwai
The power to call in a Para Drop of troops was a promotional ability that could be granted to all American generals and one Chinese general (General Fai) when they reached a certain rank. In both cases, there were 3 ranks of Para Drop, each granting an increased number of troops - 5, 10 and then 20 for ranks 1, 2 and 3 respectively. A Para Drop could be directed to take place anywhere on the battlefield, with the troops delivered by cargo plane(/s) - Rangers for US generals and Mini-Gunners for General Fai.
The Para Drop was most useful for taking enemy generals by surprise, dropping troops into poorly-defended areas where they could quickly capture facilities and overcome the opposition. Naturally, dropping soldiers into an area populated by enemy vehicles was not typically a good idea.
