Danish mechanised infantry platoons were of 3 squads, each of 10 men. Two of those would be crewing the M113, so eight dismounts. An MG3 (M/62 LMG) per squad along with an 84mm Carl Gustav (M/79) and the rest with G-3a (Gv M/66).
There's a PHQ element of four men that includes a 60mm light mortar (M/51) whicg was apparently the old US M2 mortar . Apparently there were 2 tripods/ lafettes held for the machineguns and enough IR scopes for 1 per squad.
All that comes from the article on the Jutland Dragoons in 1985 cited above. Click on the badge in the following link and you'll get the original PDF in Danish.
