This bugs me, because it confuses things.
I always assumed, in cmbo, that 'sneaking' meant walking very stealthily in order to minimise noise; whereas crawling meant hugging the ground to minimise your visibility and maximise concealment. Its very difficult to crawl quietly as you are dragging the whole of your body's frontal surface area (let alone whatever equipment and accoutrements you might have about your person)across the surafce of the ground. disturbing the rubble, leaves, etc that will make a noise.
Why then, in a night scenario, when i want to sneak up on a position do i now only have the option for my troops to fling themselves face down in the mud and drag themselves along disturbing every pice of debris in their path?
Is "advance" the new "sneak"?
