That is the entire point of all of my responses in this thread. You go INFANTRY with ARTILLERY. Allied artillery is superior and can do more devastating strikes because you face lower entity squads.
Allied artillery isn't superior in any way. UKF and USF cannot even field proper artillery without commanders.
The general problem of the Infantry+Artillery combo is: It works until the axis bring the counter. The counter will usually be something like:
->KT+JP4+Stuka
->JT+P4+Stuka
->Ele+Brummbär+Panzerwerfer+Offmap
->Ele+P4/Ostwind+Offmap
-> so in general: strong AI tank + strong AT tank + strong Artillery unit/offmap, supported by sporadic infantry
Speaking about lower entity squads: ... tell that the USF/UKF players who go up against OKW with Pfusiliers and Volksgrens. Soviets are dead in the endgame anyways, unless they receive life support from USF or UKF.
