never much seen the point in doing a bare heading a heavily armored tank.
Bit like swapping the main battle tank cannon for a lance so you can drive up close to stab the enemy tanks with it..
Never much seen the point worrying too much about modifying them either though - ok they are now expensive on ebay etc, but were in essence mass produced, and really, your helping maintain the value of the unmolested ones..
That and they are your toys, so have at it, its not like they are Fabergé eggs you have decided to scramble.
Also the work done really looks good, its achieving what you want and the aesthetic etc, so yay!.
In other words if you want one who got shipped to battle before they could screw his helmet on - make sure he looks really annoyed about it as every one is trying to shoot his face off.
