Training the Best

This is the high speed new oxygen mask that I get to wear. The helmet in the center is the same model that I wear (The HGU-68/P). The one on the right is mounted with night vision goggles (I won't get those for some time), and the one on the left is just for a different angle. The 23 is much more comfortable and less fatiguing to breathe through than the older 17 model which they are slowly phasing out.
