On such a small map I'd use APC's merely if I cannot afford "real" tanks and enemy is supposed to have weak AT defenses, and I don't use them as transports per say but as mobile MG pillboxes or to have a rapidly deployable reserve. Or, if possible, i buy some cheapo old reserve tanks instead (for Czechoslovakia my favourites are T-34/85!s, well into 1980's still in reserve depots
)
