aight since there was a C thread in the deuce section it got me to thinking what does the X in XM818 mean?

at first I thought it meant winch. but not so as I've seen some xm's with and without winch. so anybody have any ideas?

X means experimental model... Before the M-1 tank was the M-1 tank, it was the XM-1.. When an item gets adopted, it "looses" the X designation

looses is for nooses.... loses is short for lost.... ACE

I thought it was for X rated, because they thought it was such a "sexy" truck !

X indicates that it has not yet been type classified by the Ordnance Committee. T designates experimental in vehicles. X in aircraft is experimental. Hence, the T41 experimental tank became the M41, while the XP-51 Mustang became the P-51 (later F-51) fighter.

Hope this helps,

Before adoption of the "X" prefix before a model number, such as "XM-1", the Army used the "T" prefix, as in T-1. T for Test. The Army dropped it around the late 1950s, perhaps a little earlier.

Interesting! In your XM818 are the data plates "normal"? I would like to see a photo of your data plates and any one else who has a "X" model. I am really interested in the XM381 4x4 two ton.

I will try and get a pic of the data plate for you but it looks normal.

My XM818W/W Data plate looks normal. I have yet to figure out what part of my truck is experimental. although it does have a Tach O Graph and i have wondered if that was the reason it has an X.

Perhaps the date of manufacture will provide a hint.

The XM757 8x8 truck tractor and the XM791 van body remained "X" until they were retired. The manuals even labeled them "X". The only 8x8 in the series that was an "M" was the M656 cargo version.
