Thank you, once again, for the question. I'll begin the answer and my colleague may complete it.
There is a certain hierarchy among the trades when it comes to the maintenance of all of our equipment. There are responsible engineers and technologists, that is to say those who do more advanced maintenance; there are also technicians. This is quite complex work, whether we are talking about fighter aircraft, submarines or combat ships. It's really quite complex.
There is also the fact that we compete with the private sector to recruit personnel. People need specialized training, and it takes years. This makes it difficult to hire people. For some trades, the basic training can be done quite quickly, in a few months. However, when it comes to technicians, it often takes several years before they can work on their own.
