Yes. I think you have to put things into perspective. Saying that it would be desirable for all instructors at the national schools to be bilingual is one thing, but saying it's achievable in spite of the way in which people are posted, the operational tempo, etc., is another.
In addition, some courses are given exclusively in French and others exclusively in English. So putting bilingual people in duties in which they will teach only one course in English or in French means that a given bilingual person may not have a bilingual position elsewhere where that person could be in a better position to serve the institution.
To go back to the point raised by General Semianiw, that's why the commanders are accountable. When functions are designated, we do the rounds. The commanders have to ensure they have the necessary staff, with the necessary language capability, to deliver the goods. Here, for example, you have two commanders: Colonel Hamel and Lieutenant-Colonel Whelan. They have to ensure they have a core of instructors, with the required language skills, to deliver the goods they're asked to deliver.
