@RTS354 I looked into your MGRS issue and noted the Axeman JTAC unit provided the coordinates of GG32313599 and an elevation of 35 feet MSL. Using just that information alone, we know those coordinates have a precision level of 10 meters (GG 3231 3599 when split apart for easier reading -- each section has 4-digits).
The F-18's UFC, which I suspect your post may apply to, only supports MGRS coordinates at the 100 meter or 1 meter precision level if memory serves correctly. You can get fairly close to your target if you just remove the last digit from each section before entering them into the UFC. GG 3231 3599 would become GG 323 359, so you'd key a value of 323359 into the UFC after selecting GG from the grid list.
Alternatively, if you have the PRECISE mode enabled for your coordinates in the F-18, you can simply add a zero to each section. GG 3231 3599 would become GG 32310 35990, so you'd key a value of 3231035990 into the UFC after selecting GG from the grid list. The PRECISE mode can be enabled before adding your coordinates in the UFC by pushing the related OSB button:
Since the JTAC unit hasn't provided coordinates at the 1 meter level, your TGP won't be exactly on the target the JTAC wants you to engage, but it should be fairly easy to locate them based on what you entered there:
Hope that is helpful!
