Both army and navy were mostly equipped with obsolete weapons and equipment. The uniforms, however, were of good quality, and suited the Norwegian terrain and climate very well.
Brown leather belts with straps and ammo pouches were used, together with a gas mask in cloth bag. A big green rucksack was also common.

The uniform was grey-green (almost bluish), and there were 3 basic kinds of tunic:

Thick woolen socks and good quality ankle boots were used.

Service head dress was a stiff kepi, with black leather peak & chin strap, and lace of braid according to rank. A cocarde of the National colors, red, white and blue, was in front.
The most common head-dress during the invasion, was the ”Finnmarkslue”, a soft field cap with matching peak and ear flaps piped in red, which fastened at the side of the cap with a button and cloth cocarde.
However, during the first days of the invasion, many had only a few uniform items, quite vigilante like.
Steel helmets were rarely worn, the army had the Swedish M1921 helmet, adopted as M/1931. It had an oval stamped badge bearing he Norwegian Lion stamped to the front. Some branches, like artillery and cavalry used the British ”Tommy” helmet, also with badge.

Norway had no anti-tank weapons, sub-machine guns, nor hand grenades or land mines.
The Anti-aircraft artillery was scarce and obsolete. The few field guns were mostly 7,5 cm howitzers or 6,5 cm mountain cannons..

Rifles
Norwegians have a long time tradition for being hunters or performing shooting as a sport, so most were quite familiar with the Krag-Jorgensen rifle, 6,5 m.m. A good weapon, but had it's weaknesses too. Introduced in 1894. Good precision weapon, but needed to be properly used and maintained. Bayonets were used whenever available, and scopes were not unusual.

Automatic weapons
Only a few men were educated on these, so in many cases the officers had to function as MG-men.
