In a state of high readiness that's true but over a protracted period it is not effective or realistic to have that level of alert. What happens if you in an OP for a month and nothing happens? Troops lose their edge and effectiveness over time at that level. That may be good for training but in the field that is courting disaster.
I'm not saying that they should be fully kitted up at all times but unless washing you should have, at the very least, your trousers on and possibly t-shirt with everything else like boots, body armour, helmet, webbing and of course weapon close to hand.
