The Sisu A2045 HMTV (High Mobility Terrain Vehicle) is a Finnish standard medium tactical truck, intended to replace older SISU A45 "Proto" light trucks in the Finnish Defence Forces. In spoken language Sisu A2045 is called the MAN-Sisu referring to the engine, axles and other elementary parts delivered by the German lorry manufacturer MAN Nutzfahrzeuge,{{cite web|url=http://www.boy.fi/atk/jatkuu/30092008_ProtoSisu.php|title=Tällainen on Proto-Sisun seuraaja|language=Finnish}} officially MAN SE, former MAN AG. For the personal transportation on the installed seats, twelve persons can travel outside the driver's cabin. The lorry is classified by its weight as a middle off-road logistic vehicle.

The trucks are used for general logistics and conscript training, as well as for towing artillery pieces, anti-aircraft weapons and command modules.

Sisu A2045 is the successor of Sisu A-45, Sisu AH-45 and Sisu KB-45. The A2045 was introduced at the Security and Defence 2008 exhibition in Lahti, Finland.{{cite web|url=http://www.sisudefence.fi/node/14|title=SISU A2045 4×4 off-road logistic vehicle introduced at Security and Defence 2008 exhibition|publisher=Sisu Defence|access-date=30 May 2012}}
