Best Uses/Practices for: 2 man LMG units

[PoorOldSpike]

A Tankhunt team will easily spot enemy tanks and vehicles without binocs (can't miss 'em), and he'll also spot enemy MG's and Infantry, even if they soon change into icons.
See, the icons tell me where the enemy are and that's all I need to know, why does my TH guy need binocs?
(Anyway I can tell if its an MG or infantry by the sound they make when firing)
