The state working group set up at the beginning of 2019 under the leadership of the 3rd Riot Police Division cooperated with the Cologne Sports University. The university's broad-based study made scientifically sound statements on weight load and temperature development during typical missions. The requirements were developed together with the specialist departments of the higher state authorities (LZPD and LAFP). In addition, the experience of other working groups of the state and federal police forces was also incorporated.

For four weeks, the colleagues put various items of uniform through their paces in an operational course developed by the LAFP. This is where the wheat was separated from the chaff. Some proved to be good and passed the practical test, while other products were rejected. The vote of the colleagues ultimately led to the procurement of the current KSA.

In addition to the integrated impact and stab protection, the new KSA also has permanently integrated ballistic protection. This coordinated system in a vest model is much easier to wear and offers greater freedom of movement. Helmet, radio or bodycam can be attached directly to the vest, as can pockets and license plates.

In addition, the material is flame-retardant, water-repellent and easy to clean.

The KSA can be quickly removed using quick-release fasteners (emergency openings). On hot days, the KSA can be aired out to cool the body in quiet situations.
