Ok lets discuss this fight. Jackals don't get any vehicles except for drop ships. The jackals get all jackal weapons (in adition to needlers and plasma pistols) ,but most of them will have shields and plasma pistols. Gungans get their shields (which are much mroe powerful then jackal shields) plus emp grenades or their sheids plus spears. Some gungans will have their animals they ride on plus spears and some jackals will have ranged weapons (like carbines and beam rifles). Gungans also get their animals with force fields that can protect them against jackal snipers unless they get close and walk though the force fields. The jackals will also get skirmishiers and all jackal ground weapons (including their knives).
Round 1: They fight in open plains and grasslands. Both forces have thousands of troops scattered in various battlefields. This is the most balanced enviornment for both teams.
Round 2: They clash in a jungle. This enviornment will favor the jackals and their stealth skill. This time gungans won't have animals with shields to protect their armies from snipers or ranged attacks. However, the gungans will be able to hide in the jungle.
Round 3: The two teams will fight in a swamp-like enviornment. This enviornment will favor the gungans where the gungans can hide and jump out of the swamps and attack with the element of suprise. The gungans can also stleath attack the jackals and they are used to being in swamp and sea enviornments.
