Is field artillery officer dangerous

Answer 1

Yes, but nowhere near as dangerous as being an infantry officer or a combat engineer officer. Both of the latter put a man much closer to the direct fire of the enemy. Artillery was usually a few miles behind the front lines and adjusted its aim by receiving directions from a Forward Observer, communicating by means of radio or field telephone. Forward Observers were artillery officers, but they were on the front lines with the infantry, so they could see where the artillery should be aiming. Forward Observer was the most dangerous job in the field artillery.

Artillery was a target of the enemy, and if they could get a fix on its location they would fire their own artillery at the positions of friendly artillery, in "counter battery fire", and this was a hazard. The US was usually much better supplied with artillery ammunition than its foes, though, and probably did more counter battery firing.

Sometimes if the enemy made a successful attack and achieved a breakthrough, they would get in the rear of Allied lines and be back among the artillery before anyone knew they were coming, or before they had time to "limber up" and bring up their trucks, hook up their howitzers and pull back. There were instances where artillery batteries had to fire at visible enemy targets, over "open sights", which was considered point blank range for artillery. The enemy would of course be trying to shoot battery personnel in these encounters.

Answer 2

Yes they are. It is a weapon of war and is designed to kill people and destroy things.
