This is a genre of anime which features mechanical fighting machines. Often these take the form of giant robots but this isn't the only form mecha can take. There are tons of examples of mecha titles considering the popularity of the series. Blue Gender, Shin Seiki Evangelion, Tenkuu no Escaflowne, and Bubblegum Crisis Tokyo 2040 are all classic mecha titles.
Titles of this category should cover the events of a war as significant element of the storyline (even if the actual conflict doesn't get that much airtime). The opponents should be nations at least (alien races, star systems, parallel universes etc. are fine as well); conflicts between smaller organisations would rather be categorized as "fighting".
An example for a real-world war would be Hotaru no Haka, a fantasy war would be Lodoss Tou Senki (OAV), a SF war would be Saishu Heiki Kanojo.
