Rapid reaction force

A rapid reaction force is a military or police unit designed to respond in very short time frames to emergencies. When used in reference to police forces such as SWAT teams, the time frame is minutes, while in military applications, such as with the use of paratroops or other commandos, the time frame is hours to days.

Rapid reaction forces are designed to intervene quickly as a spearhead to gain and hold ground in quickly unfolding combat or in rather low intensity conflicts, such as uprisings that necessitate the evacuation of foreign embassies. Because they are usually transported by air, such military units are usually lightly armed, but often extremely well trained to compensate for their limited to small arms and light crew-served weapons and the lack of vehicles, armor and heavy equipment like tanks.
