Sappers

The sappers technically arent considered a different type of unit in warbanner, but i think it is appropriate to make a separate article about it, as the game considers them melee infantry, and technically they are, but its widely considered that they have enough differences to be a kind of unit of their own, the main difference being that there is no sapper that dosnt carry with him the perk "sapper tricks" that allows them to ignore artillery damage almost completely, this allows them to cover most of the army from cannonballs, artillery, mortarmen explosive ammo and hand grenades, also sappers have a bigger regiment size than most other melee infantry

Strategy
the sappers are often used to cover other troops at the start of battles where the enemy has a lot of splash damage dealing weapons, like cannons, but also from mortarmen, having the perk "sapper tricks" gives them high resistance to that type of damage, and often, if one or more groups manage to get behind enemy lines, and get to the fortified zone of the defending army (if used in a siege) they can be very effective, especially Brunswick sappers that have a perk that boost their damage against structures, and if they encounter a line and start a melee fight, use a bandage and defense order on them to keep them alive, that gives them chances even against the higher numbered line infantry, and often, one of the hardest things to counter in the game, can be an army of sappers with field doctors behind them, they can barely take damage at all, and if a large group of sappers (multiple regiments) advances with field doctors squads behind them, its unlikely that unless the enemy haves a lot of light infantry, heavy riflemen or dragoons, they will be able to stop the sapper horde easely, those are just a few ways to use this types of units, go out and experiment yourself! there is surely more ways to use this powerful units, also, another thing that distinguish them from the normal melee infantry is that they are actually fast

Pros

 * 1) very high health
 * 2) high regiment size
 * 3) very good melee
 * 4) good at destroying structures
 * 5) almost immune to artillery damage
 * 6) very fast melee troops

Cons

 * 1) light infantry, heavy riflemen or dragoon spam will usually stop them fast
 * 2) low availability
