More M113 variants, this one is an air defence vehicle from Singapore.
Like the M113 that mounted a ZSU-23-2, this is a US vehicle carrying a Soviet/Russian weapon system - the 9K38 Igla IR-homing missile.
Damn! If I keep this up I'll be the M113 fanboy of the forum but at least I won't be as bad as "you-know-who-who-wants-all-M113s-called-Gavin" hahaha!
