Daniel Davis recollections are endlessly amusing:
One thing that you tend to pick up pretty soon when working for a Swiss company, unless you are very unobservant indeed, is that the senior Swiss guys all know each other because they’re all in the Army together. It is possible to opt out of continuing service in the Swiss Army reserve after you’ve done your compulsory duty (and even that can be done in non-military service). But this doesn’t seem to be the way to a successful career if you want to stay in Switzerland and be a business executive. So Switzerland has an army of middle managers, which in my opinion is probably a pretty frightening prospect for anyone thinking of attacking them, as these are middle managers who have been given a single aim (defend Switzerland) for decades, plenty of time to practice and budgets which have to be considered for practical purposes to be inexhaustible. That’s the sort of situation that can get aircraft hangars built into the sides of mountains, tunnels that double as horrific tank-traps and Alpine passes that can be rendered impasses at the touch of a button. Even the low-lying cities like Basel would, according to highly classified rumour, be able to provide a number of nasty suprises to any machanised army which decided to detour through them.
The thing that the Swiss Army hates above all else, of course, is helicopters.
