In order to use the Sand Mice, you need the Sonic Summoner, which you can get by winning the hoverboard race on Rilgar and taking the prize from that to Skid McMarx's agent on Aridia.
Once you have it, go to Batalia, take out everything but the tanks, and go behind the building by you ship where the Sand Mice can be found and equip the Sonic Summoner. Then just go back to where the tanks are located and let the Sand Mouse take it out. Just be prepared to get up close and dodge fire.
NB, it will probablt take 2 or 3 sand mice at least to take out all the tanks, so you'll be making several round trips to the levels start.
