Even though the exhibition was not held in a military base, it was full of military personnel and police. So one wrong move and you could end up in handcuffs. Discipline and safety.

You must have misunderstood something, as only one mobile kitchen is old, the rest is NATO standards, which can be called ultramodern.
Alright. Thanks for the clarification.
