As for favorite troops, it's more difficult to single out any individual army as there's so many that stand out above the rest. The Timmee Vietnam series and its variants is an easy contender, as are WW2 American GIs, Japanese infantry, British tommies... But I think I'll give special mention to Germany's Afrika Korps (seen here
>>6349351 and
>>6386944) for the excellent selection of fighting stances, an actual loader for the machinegunner and a badass Rommel pose.
Pic related are some of the runners-up, an anon made this edit some time ago and I still find it funny as hell.
