Hi,
It is like getting back to a new country (well we said the west bank is like a different country 🤔) and the learning a language.
Most of the time when we called to military reserve we practice. That means we are only us, without the mandatory. Now we were called to serve and protect in the west bank and we are work with the mandatory army. And those goes forward….
Like any language, it lives and changes. We sit down in the auditorium and listen. half of the words we don’t remember and half of those words are new. Add to it the fact that this language have something unique – it keeps making things shorter by using acronyms. You are familiar with the phrase but only later you realize it became an acronym 
Take Care
