walk with a signalling light attached to the top of his helmet
That was me in 2001 during basic training (one of the last conscripts in Germany). When we marched to the firing range I had to wear a blinky light right on my helmet. It was embarrassing, but so is the whole service if you are not really into that stuff.
You can put cucumber in almost anything that is not cooked, doesn't matter if sweet or savoury. Cucumber-Apple-Salad with a nice sweet and sour yoghurt vinaigrette is the bomb.
