There are no rules for Krav Maga fighting, and no built-in distinctions in training between men and women.<8> It has no sporting federation, and there are no official uniforms or attire, although some organizations, internally, do recognize progress through training with rank badges, different levels, and belts.
Techniques generally focus on training combatants in conditions approximating real-life scenarios. Krav Maga trains combatants for situations where losing would be potentially fatal. Its attack and defense maneuvers aim to neutralize the threat and facilitate rapid and safe escape. These include a variety of fast and fluid crippling attacks to vulnerable body parts through various efficient and often brutal strikes. The improvised use of any available aids is encouraged - maximizing personal safety in a fight is emphasized.
Krav Maga training programs involve rapid learning, with offensive and defensive techniques introduced from the first lesson and retzev (pronounced ret-zef and meaning "sequencing") playing an important part in both training and maneuvers.<9>
While no limits are placed on techniques to be used in life-threatening situations, during training the legal need to minimize damage is generally stressed (at least in civilian contexts), and instructors are required to demonstrate how to moderate the techniques to suit the seriousness of the circumstances.
Training will also cover situational awareness in order to develop an understanding of one's surroundings and potentially threatening circumstances before an attack is launched. It may also cover "Self Protection": ways to deal with potentially violent situations, and physical and verbal methods to avoid violence whenever possible.
