My suggestion if you are in the public say on the train or busses, etc, and especially when you are alone, it might be best to travel in civvies with your uniform, etc in a kitbag or better yet keep a uniform at the unit in a locked locker.
There is too many arseholes out there, and many do not have the same view as you would expect.
Here in Australia onwe is not allowed to be in the public unless there is two or more, all due to the threat against us, and alarge population of ethnics in certain areas, where defence people and even their cars have been targeted.
Its for our safety.
Sad, but true in todays society ther are many people out there who are true army haters/haters of the west, righ here in our own countries.
