I am planning to use an element of mounted infantry on Monday in my HYW English army. As far as I can see, the Mtd4Ld functions as ordinary 4Lb except it can move at 3Bw per PIP and for up to three moves per bound (with the usual conditions). I am pretty sure there is at least one other difference, related, perhaps, to being recoiled in bad going, but can I find it??? Could anybody please give me a summary of the other differences, if any? Thanks.
Mounted Infantry rules are spread around the rules
This part is in Troop Definitions "A very few armies have mounted infantry (prefixed by “Mtd”). These are on larger bases with their mounts, but remain foot and differ in that in good going they have the same tactical move as knights and can move more than once per bound."
The cryptic part "they remain foot" is supposed to indicate they act exactly like their foot type -- Mounted Bow act like Foot Bow except ...
This is in the Basing Your Models "Mounted Infantry are based as 3-4 foot figures plus a vehicle, led mount or mounted figure. "
This is in the deployment section "Cavalry, Light Horse, Camelry, Mounted infantry and Auxilia or Psiloi must deploy at least 2 BW away from battlefield side edges and others at least 4 BW away."
This is in Tactical Movement section "3 BW If Knights, Elephants, Camelry or any mounted infantry and only in good going, or if “Fast” foot in any going."
This is in the second move section "(a) Light Horse or mounted infantry; and making a second or third move that is entirely in good going."
This is in the Side Support section. You must infer that the rule applies to Mounted Bows if solid as they they remain foot "“Solid” Bows add +1 if supported by “Solid” Blades."
In outcomes, another place for inference, for Mounted Lb and Mounted Cb "If its total is equal to that of its opponent: Knights or Camelry Destroyed in close combat by any Blades or any Bows that are Lb or Cb, " There are Mounted Lb and Cb
for example: IV/43b Hungarian Army for the Crusade of Nicopolis 1396 AD: 1 x General (3Kn), 1 x Hungarian nobles (3Kn), 4 x horse archers (LH), 2 x crusader knights (3Kn), 1 x crusader crossbows (Mtd-4Cb/4Cb), 1 x spearmen (Sp) or crusader ribauds (5Hd), 2 x archers (Ps or 3Bw).
This is in the Beaten section "If its total is less than that of its opponent but more than half: Destroyed if sacking a city or if defenders of a city, fort or camp or denizens or camp followers that have sallied or mounted infantry in bad going."
It is important to note that there are many references to "mounted," such as in combat factors and outcomes, but this does not refer to "mounted" infantry, which as noted in the first example, "remain foot."
Also note that while Phil uses the generic term "mounted infantry" there is only one type of infantry that is mounted, and that is Bows. There are types that dismount from being mounted to being foot such as 3Kn//4Bd. There are 3Cv//3Bw, but these are not mounted bow, these are cavalry that convert into bows -- mounted to foot.
