After WW2 the Danish Army wore the British Battledress, designated M/44 by the Danish Army. This was replaced by the M/58, a uniform based on the contemporary American uniforms. But it was in the late 70ies decided to replace this with a camouflaged uniform. The German Army had at that time conducted a series of tests that led to the Flecktarn pattern. This was tested by the Danish Army, but in a modified form with a reduced number of colours - 3 instead of the Bundeswehr 5. Measurements of the Danish terrain led to the colours chosen for the M/84 pattern. This research led to the introduction of the T/78 uniform. The "T" designates that this was a test uniform. The T/78 was tested by troops. The lessons learned by this led to the M/84 uniform. There is a number of differences between the T/78 and the M/84.
The pattern: the overall pattern is the same, but the green part of the T/78 is more "khaki" whereas it is more green in the M/84. The uniform: the cut is in general the same, but press-buttons have been used instead of some of the buttons of the T/78.

A 20 by 20 cms view of the T/78 pattern:
The pattern was worn from 1978 and a couple of years after the introduction of the M/84 (to wear out stocks) by selected units.
The clothing for the T/78 was made in France, wheras the clothing for the M/84 (at least initially) was made in Denmark. According to some sources this is the reason for the change of colouration between the T/78 and the M/84.
