Is the last FM or TC version of a manual still necessary when a new ATP version is put out for the same manual?

Specifically, the newest version i can find of 3-20.98 is ATP 3-20.98 dated April 2013, but there is also still FM 3-20.98 dated August 2009. The problem is that the FM is about 3 times as long as the ATP. Is that normal for a new version to be condensed that much?

ALways look at the into pages of the "new" pub, it will have info if it supersedes, supplements, or something else.
"ATP 3-20.98 dated April 2013
*This manual supersedes FM 7-92, 23 December 1992 and FM 3-21.94, 18 April 2003. "

Check the 25-30 at apd.army.mil to see which is most current. Anything that has been superseded will show accordingly.

One reason the ATP may be short than the old FM is they may have taken some info out and put it into an ATTP, ADP, ADRP, or a TC. They all cover different portions of the same types of operations. The number should still be the same to help you identify what those different pubs cover. Army Publishing Directorate does a pretty good job of identifying which pub is the most recent, and should be used.
