Ostheer has to deal with T70, Stuart, AEC. What light vehicle do Ostheer’s opponents have to face? The mighty 222?
The reason the mg42 is better at fighting off LVs is that it compensates for Ostheer’s nonexistent LV play.
221, 222, 251/flame halftrack, 250 halftrack, puma, luchs, flack halftrack, kubelwagen (lel).
OKW exists. Ost halftracks exist.
The MG42 is also basically a waste against the T70 unless point blank and rear armour, but the differece it makes against the early light tier vehicles is extreme.
