specifically henry weapons that seem to change the course of this war? >> in a different times, early on was the javelins, you remember the soldier firing missiles, more recently himars long rabatits, and drones. let's talk about the javelins for a. moment these were key early in the war when russia was making its mad dash for kyiv. highly mobile shoulder fire really neutralized. -- >> mystery hundreds of russian tanks. himars more recently longer -- highly accurate it has been able to make a difference in the eastern battlefield today. which is a rocket in artillery war, particularly high accuracy and they're using u.s. intelligence to hit those russian targets. we go back to drones, also long-range one that's really made a difference there is the empty, arctic-ish may drown, i should make the point though, these weapons can go in both directions, russia has done it numerous amount of damage or drones, particularly with those supplied by iran.
