It is a two-engine attack helicopter designed for close air support of ground forces against armoured targets, and for transport of personnel. It has a classic design with a five-bladed main rotor and a three-bladed anti-torque tail rotor.

Similarly, Period Betting for hockey is available (i.e. 1st Period Result and 60 Minute Result). Draw/Tie No Bet. "Draw No Bet" or Tie No Bet  is where it is possible to bet on either the home team or the away team. It is also common practice to refer to "Tie No Bet" in cases where no tie odds are offered.

A Tie No Bet is a bet on which team will win the game outright. This differs from a Moneyline bet because Draws are not an option. If the game ends in a tie, the bet is ruled a push and your money is refunded.
