The anti-armour and heavy-weapons hand: every launcher and its rounds, and the gun theory behind them.

A skill is yours wherever you sit: it is on your TAC//PAC record and comes with you into any slot. In game it shows as HVY on the squad panel.

• Carry and fire the team's anti-armour: NLAW, MRAWS, Titan, RPG, M72, Mk153, Spike.
• Pick the round for the target - HEAT, HE, airburst, guided - and the range it works at.
• Lay the machine gun when the team has one: beaten zone, grazing fire, rates of fire.

• The heavy-weapons arsenal: every launcher and every round. None of them is in the common arsenal.

• Heavy weapons: aiming devices, mils and MOA, machine-gun theory, light anti-armour theory, armoured vehicle weaknesses.

By doing it. There is no course to pass first: show you can do the job on an operation and staff put the skill on your record. If you want to be taught, ask - we will make the time.

Still to be written.
