What is inter-theater movement vs intra-theater movement?

• A. Inter-theater is movement within a theater; intra-theater is between theaters.
• B. Inter-theater is movement within a theater.
• C. Inter-theater movement is between theaters; intra-theater is movement within a theater.
• D. Inter-theater is for personnel only; intra-theater for cargo.

Answer: (C)

Inter-theater movement covers moving assets from one theater of operation to another—across geographic combat zones. Intra-theater movement is moving assets within a single theater of operation—inside the same geographic area. The correct idea is that inter-theater means between theaters, while intra-theater means within one theater. For example, moving forces from the U.S. to Europe is inter-theater; moving troops from one city to another within Europe is intra-theater. Other options mix up the scope or reverse the meanings, which is why they don’t fit.
