Which feature distinguishes an MTOE from a TDA in the UIC?

• A. The leading alpha character in digits 2-4
• B. The first digit
• C. The last two digits
• D. The three-digit suffix

Answer: (A)

The marker used in the UIC to tell MTOE from TDA is found in the middle portion of the code. In the second through fourth positions, an alpha character appears for MTOE units, signaling a Modified Table of Organization and Equipment. TDAs have those positions as numeric, so they lack that letter. The rest of the code—the first digit, the last two digits, and any suffix—don’t indicate the type, so they aren’t the distinguishing feature.
