As Vermis said, there are a
ton of suppliers for modern figures in larger scales; 1/35 figures are widely available for the vehicle models in this scale, with 70mm, 90mm, and 120mm figures also available. For example, the
Black Dog 1/35 resin figures,
Accurate Armor figures, Academy, Tamiya, Trumpeter, and many small companies producing resin figure lines. You can look online at any of the plastic military model kit dealers, and another possibility is to look through the announcements in the 'Figures' forum at Armorama.com to find companies producing figures individually or in sets.
