Decdicated Transports share the force orginaistion chart with the unit they are assained to but count as a seperate unit while on the field. For example if you have 2 Rhinos with 10 Marines in each then both the Rhinos and the Marines count as troops(total 4 troops).
The ONE landriader pit means that only 1 Assault ermintor unit can tkae one so if you have 2 Assault termintor units only 1 can tkae a landraider. the also applys to normal termintors so in a normal Marine list the max number of Landraiders you cna have is 5(2 will be dedicated transports)
