That's insane and totally unthinkable before this all unfolded.
In storage is basically a scrap yard - the combat vehicles could be used, but would be in a poor material condition and have the equipment they were parked up with. If you think the armour they using now is having a tough time - imagine a tank with a huge IR searchlight for its night fighting! A soldier with night vision goggles would just see the huge light at night and shoot at it....
