IVAS is a single platform that features an all-weather fighting goggle and a mixed reality heads-up display that integrates next-generation situational awareness tools and high-resolution simulations to provide Soldiers with improved mobility and lethality, during the day or at night.

An Individual Voluntary Arrangement ( IVA ) is an agreement with your creditors to pay all or part of your debts. You agree to make regular payments to an insolvency practitioner, who will divide this money between your creditors. An IVA can give you more control of your assets than bankruptcy.

The martingale strategy fails even with unbounded stopping time, as long as there is a limit on earnings or on the bets (which is also true in practice). It is only with unbounded wealth, bets and time that it could be argued that the martingale becomes a winning strategy.

Summary: The Martingale Strategy states that when a trader experiences a loss, they should immediately double the size of the next bet. By repeatedly doubling the bet when they lose, the trader will theoretically even out with a winning trade at some point.
