When says the beamer has an "Anti-Armor" ability, I think it means Jeeps and MAXes, not tanks, that would just be reduculous.
I doubt the ARs and most other weapons of that sort will only be able to do very minor damage to tanks and such. Skeeters and Buggys need to worry about them though, particularly the Chaingun and Gauss.
Flares should be considered in order to have a chance to break a striker's lock, but they wouldn't have much use to the TR then.
I can't wait to get a decimator indoors.
