raid

'Raid' means a sudden attack or incursion against an enemy or target. 'Blitz' (a concentrated attack), 'incursion' (a hostile invasion), and 'assault' (a physical attack) are all synonyms referring to aggressive military-style attacks. 'Tax' is a government levy or financial charge, which has nothing to do with attacking or raiding.
