On the other hand, many Axis doctrinal units have snares even if they aren't designed as mainline replacements or dedicated AT squads: Osttruppen, Jager, Fallschirmjager. They have mainline replacements that also have snare OR AT upgrade (Panzerfusilier) as well. That's 3/4 combat capable infantry squads that can snare and also fight well against infantry at all stages of the game (if we ask Hans, that's 4/4). Meanwhile the Allied snare call ins are... Meme AT Partysans, AT Section, or Cav Rifles. The only combat-capable squad is Cav Rifles, which is 1/3.
Additionally, Fallschirmjagers can stealth + Faust, and Ambush Camo Grens can do the same. These doctrines are generally a lot more competitive choices than Soviet Tank Hunter or Partisan tactics, which include the only Allied units capable of doing the same.
You seem to forget about ptrs penals (non doc), guards, riflemen, UK engineers and sections from som commanders - they all can have 2 AT solutions avaliable on one unit (no axis infantry can do that unless by picking up dropped weapons). It can be really deadly to have a snare and bazookas/ptrs etc on one unit. Additionally, allies are not forced to equip bazookas/piats/ptrs on expensive anty infantry squads - they don't have to sacrifice anty infantry capabilities of expensive units to have hand held ATs. Especially the second ability (giving cheap units hand held ATs) is imo sth that should be addressed and more balanced.
