Pack transported artillery (and HMGs)
Mule and llama transported.
Mules cost 2 points each and move like infantry. You need 3 mules for the gun, one for the 2 wheels, carriage and barrel, (or base, stand and barrel for a mortar). A couple of extra mules for ammunition would look right to, but these would NOT count as pack train and transport units as per the Colonial rules.
If the gun starts packed on the mules then the procedure for un-packing and setting up is as follows:-
1, Play a special action order to unpack and assemble the gun.
2, Play a second special action order to prepare the gun for firing.
3, Play now proceeds as normal for the gun type.
Ox, yak and water buffalo transported.
As mule transported except may not use a move fast order.
Horse, camel or reindeer transported.
Horses, camels and reindeer cost 5 points each. As mule transported when gun is packed, but follow normal cavalry rules when guns are unpacked. Therefore the crew could abandon the guns and mount the horses, and would then count as cavalry, if there is not more than twice as many crew compared to the number of horses.
Elephant transported.
Elephants cost 9 points each. As Ox transported except you only need one elephant per gun.
Only the following may be pack transported, light mortars, mortars, light field guns, rocket artillery and HMGs. I see this as more appropriate for an ambush type scenario.
