RE: Military Loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I?m narrowing the search.  I have determined that I need Army Technical
Manual ?TM 5-312?.  It has something to do with the design of military fixed
bridges.  Unfortunately, I can?t locate this document.  I tried the army
engineering page at, but they skip that

Anyone out there know where I could find this document?
