Sunday night was game night. Some interesting points. Most of my players grew upon on 4e. In 4e the helmet is described as having an open face or a closed face. The player decides and of course you can not (normally) remove the face plate. In my player's minds, their PC's are using full helmets that cover the face. So unless you can strap a Ballistic mask over that, no dice.
While talking, I had a dim memory of going hunting in the middle of winter, 30 years ago, and having to take my snowmobile helmet off because I was not able to lay down and shoot my rifle. For me at least, the helmet hit my shoulders/back and road up over my face. This all made it sit wrong on my head. I could be a mutant.
Another one of my buddies made a strong point that most ballistic face masks, are considered 3/4 masks. It fits like a (hockey) Goal Mask. Meaning full face coverage, that rolls back to cover most of the hears, up above your forehead and at least half way up your skull, and may even drop down to protect the neck. The entire mask is held in place by at least four straps that attached to a "back plate" that is positioned on the back of your head. Wearing a true Ballistic Mask makes it impossible to wear a helmet of any sort.
Their are the half varieties, but they tend to only cover the direct face, and still do not sit properly with a helm.
He was very certain that many people, especially me, got/get confused between true Ballistic Masks and the Airsoft/Paintball variety. He called me an ignorant ass, easily confused by the web. He then told me to stop playing video games. You can tell your friends by the friendly and even commentary.
This particular buddy is a purist. He also put things into perspective for me.
So this is back on me. I obviously have one thing in mind, while reality has another.
The game rules in 5e do not say if you can wear the two together or not. Not sure if that is an over site or they feel common sense should win out on this one.
At our table, last night, we decided that you can not wear the two together. This also put the Encumbrance into a different light.
So I will say, Thank you everyone. I will go back to work now and stop complaining.
