How to say "half-track" in Japanese

• ハーフトラック
  nounDenotes the half-track vehicle itself, with wheels at the front and tracks at the rear. It is simply the English name in katakana; typical contexts include military-history writing. It is a less common word.
• 半装軌車はんそうきしゃ
  nounAlso denotes the half-track vehicle. Its characters combine to mean 'half-tracked vehicle', making it the kanji counterpart of the katakana loanword; it is likewise less common and suits the same military-history contexts.

Both words denote the same thing, the half-track vehicle: 「ハーフトラック」 is the katakana borrowing of the English name, 半装軌車 the Sino-Japanese equivalent, so the choice is one of word form rather than meaning, and both are less common.
