This Means War is the third album by English heavy metal band Tank, released in 1983. On this album, the line-up expanded to a four-piece, with the addition of second guitarist Mick Tucker, former member of the NWOBHM band White Spirit. Thanks to Tucker's songwriting contributions and to the sound being expanded by an extra guitar, the band changed their music in comparison with their previous albums with longer, more melodic compositions, which helped differentiate Tank from Motörhead, the band they were often compared to.
