One of the secret weapons in Medal of Honor: Airborne is the C96 Mauser hidden in the control room on Operation Varsity. Another is the BAR which can be found by the ammo drop in Operation Market Garden.
Of course it has blood, it's a war game. The blood however is not gratuitous.
lead burning or lap joint soldering
In batteries and soldering.

Soldering irons are designed to heat up the lead in solder to its melting point, allowing it to flow and create electrical connections. The high temperature of the soldering iron transfers heat to the lead in the solder, causing it to melt and bond with the materials being soldered.
Lead "burning, Soldering with the use of lap joints
Soldering of copper is a chemical change. This is because when soldering, the material undergoes a change in its chemical composition due to the reaction between the metal and the soldering material, typically a mixture of metals such as tin and lead. This results in the formation of new compounds that bind the parts together.
Have you ever had a soldering iron roll off the table and land on your wrist, burning a hole that took over a month to heal? I did in 5th grade while building one of the Radio Shack electronics kits I had received for Christmas! Learning from that I made my own soldering stand from a small metal can and poured over a half inch of lead into the bottom from my lead soldier casting set to make sure that the weight of the soldering iron could not tilt the soldering stand!!! I was never going to run the risk of a soldering iron getting away from me again!!!!!
Airborne lead is no longer as much of a problem due to regulations that have been implemented to reduce lead emissions, such as the phase-out of leaded gasoline and restrictions on lead in paints and other products. Improved technologies and public awareness have also played a role in reducing lead exposure and pollution.
Soldering irons are usually used with rosin core solder. Sometimes it has lead in it but often not since its toxic. Most of the time its for heavy soldering like heavy gauge wires or older circuit boards since the tips are fairly big. They also have a decent temperature control so anything that is delicate like large SMD soldering.
Soldering wire is usually made of a combination of tin and lead. The most common ratio is 60% tin and 40% lead. However, due to environmental and health concerns, lead-free solder wire made of tin, silver, and copper is also widely used now.
It is not recommended to use expired liquid flux for soldering as the effectiveness of the flux diminishes over time, which can lead to poor soldering results. It is best to use fresh flux to ensure proper soldering and avoid issues such as weak joints or oxidation. Expired flux may also contain harmful chemicals that could pose health risks during soldering.
Lead was removed from solder due to health and environmental concerns. Lead is toxic and can accumulate in the environment and in our bodies, leading to various health issues. Therefore, lead-free solder is now commonly used to reduce these risks.
