When 30mm HE rounds are selected action menu shows an option to "Reload 90Rnd 30 mm (HEI-T)" which is unnecessary. This action menu option should be removed since it'll reload that mag once the first mag is depleted by default.
100MM cannon shows 22 rounds with 2 extra mags, but when first mag is depleted you will see 18 | 1. However, you can't fire this magazine and you can no longer switch to the cannon using the "Weapons group 1 Key". You have to use the "Next Weapon" or "Previous Weapon" key to go back to the cannon however you still can't fire it. After depleting the missiles it'll go back to that 18 round mag but you still can't fire it or switch back to it with the "Weapons group 1 Key", but you can switch to it with the "Next Weapon" or "Previous Weapon" key.
The missiles shouldn't be able to be selected by the "Weapons group 3 key" if possible. The in game Rhino fires AT missiles and doesn't have this issue.
