I presume there are quite a few ex / current forces on here, so a question I have pondered for a while. How has TI changed modern warfare? We all know how often TI is described as a game changer for deer stalking, so similar must apply to the battlefield? How can infantry survive against a TI equipped adversary? Likewise the big lumps of armour? If we can use it to see them, they can surely use it to see us?
