ok I worked up a quick TOE for a cav division using M-551's and M-115's
this is what I got :
I take the arm cav sq's/Battalions take away the tank company and use M-115 and not M-3 so with my cav division i have 6 armored cav battalions and 3 mech. mech battlions with 58 m-115's, armored cav = 4 ac companies each with 1 m-577, 9 m-551 12 M-115 and 2 m-106. + at battalion lvl add an HQ with around 60-80 trucks, 4 M-557's, 2 cev's and 4 AVLB's 8 m-109s and 8 m-548's (ammo)
so divisions totals is: 216 M-551's, 462 M-115's, 72 m-109's 8 MLRS ,9 cev's, 28 AVLB's, about 550 trucks and around 50 M-557's.
another way would be to dump the 3 mech battalions and add in 3 more arm cav.
