Hi!
I'm not sure if these suggestions have been mentioned elsewhere and I have just missed them, but I feel like this would be helpful to players, especially those new to the game or learning which gun is which.
1) When the "crosshair" dot is over the gun and it's health interface is brought up, just above it the circle the name of the gun should be placed.
2) When you first switch over to a new type of ammo, the name of the ammo should be presented for a short period of time on some obvious portion of the screen, then have it fade out.
This would greatly help out with learning the guns, the types of bullets, and improve the communication between the captain and the gunner.
Hope this can be included!
