nice balance
This game is about adapting to what your opponent is doing. There is no singular way to win the game. Allies who use only one infantry unit type and later 2 TDs are not competitive builds. They will get slaughtered by combined arms/aircraft support builds and never advance beyond the mid skill range ranks.
Your response lists 7 great options from our suggestions for dealing with allied meta. A faction with more options is harder to deal with (cough soviets) You shouldn't need to have all of these things, they are options! The allies also have options and any competent player will counteract what you're doing. Again, our suggestions are options. How you use the options are up to you. I would suggest checking out OKW streams to get some ideas.
AA HT - Counters all allied infantry - I would use this as a way to control any allied infantry. It also comes out at around 5 minutes and has great shock value. An allied player will try and build an AT gun or light vehicle to deal with this - so back it up with a rakten at the minimum. I find the AA HT performs best against USA and Soviets.
Puma - build this if you to dive team weapons, allied light armor and chase down 1 man retreating squads. These should be used with MG34s supporting and covering retreats. Allied players won't typically engage a puma until they have mediums - which by the time they arrive you've got a very sizeable amry to snare that medium and kill w/ the puma.
2 Rakten - This is my go to for dealing with tank destroyer spam. Two raks with snare support will decimate any tank destroyer. They can even sneak up on the flank closed and volley a TD before it can react. If they fail, you can retreat them with little to not cost to your side.
Volks - You should have at minimum 2, usually 3 of these squads to provide sufficent field presence. Use them in pairs and in green cover. MP40s or stgs are a must. Always build sandbags.
Pios - I mean these are the best starting infantry in the game .Use them aggressively in early engagements by drawing fire to the kubel or volks first. Hide them around corners. Get on top of shit for best results. You also need them to fix your tanks late game.
JP4 - Great on narrow maps; would not use it on open maps. Synergizes great with spotters. It can also cloak - meaning it gest the first shot in every engagement!
Panther - I build one of these every game. They can fight allied infantry and flank any allied armor. Keep the front facing the enemy - as it bounces pretty much every shot. Panthers are my go to repsonse to medium armor swarms.
