Ft Irwin / NTC question

Recommended Posts

Hi,

while searching for infos on the NTC at Ft Irwin I stumbeld upon a "OBSERVER CONTROLLER HANDBOOK". Inside this document are some information on "Operations Group Common Geo-terms".

Example:

CENTRAL CORRIDOR
N. WALL C. CORRIDOR
S. WALL C. CORRIDOR
MARS SITE 101200
N GOLDSTONE 115185
HILL 1297 134271
HILL 1071 152236
HILL 1003 158208
GARY OWEN 1629
HILL 1203 166273
HILL 1423 179138
ALLIGATOR RIDGE 190234
HILL 1478 196105
HILL 985 201218
NELSON LAKE 2020
MCLEAN LAKE 2127
HILL 1214 230096
KHYBER PASS 240262
HILL 1001 242244
BENCH MARK 999 251125

So my question is, what kind of coordinates are these and how can I use them to find these areas e.g. on Google Maps?

They look like MGRS numbers to me.

But didn't have MGRS-coordinates always a letter for the zone? I'm confused.

Technically yes, but if the area is all the same group(IE: AB 12345678) then its usually left out.

Anyway, those are MGRS grids. Open the map editor in SB and then open the NTC map and check the grids in the lower right corner. You will see 3 groups of 4 numbers. The first two are the grid reference and the 3rd set are the elevation. If you goto 1340 2710 then, Boom! your at hill 1297. Goto 2000 2000 and there is Nelson "lake", etc.

very nice find BTW. Now we can property name locations (those of us that haven't been there).

Thats correct, but unless there is a border in the operating area, radios calls and briefings usually just give the numbers. They always emphasis the grid reference in schools, but at unit level it kinda disappears.

Anyway, it appears that there is an area where the map sheets join on the NTC map, so you can see how much it gets used.

Thanks guys, now I can find my way around the NTC. I even found a nice plugin for Google Earth that shows me lines for the MGRS coordinates.

Dude--that plugin ROCKS! I did a quick check on some military maps of Fort Hood and Sarajevo, and the gridlines look pretty damn accurate, based on just the couple of sample grids I looked up.

Again, let me reiterate: Freakin' SWEET! :drink:

He's like Chickenman, in that 'He's everywhere, he's everywhere!"

Oh, BTW it's GaryOwen. One word. Don't make me fly out there and sing to you.
