Description:
The magnetic clamp system (MCS) was developed by Clan scientists during the Wars of Reaving as a means to improve deployment options for slower ProtoMechs by using the same process as mechanized battle armor. Based on the Inner Sphere’s battle armor-scale version of the technology, the ProtoMech magnetic clamp system made it possible for any BattleMech to carry up to two ProtoMechs into battle at a time. The technology eventually made its way back into the Inner Sphere via Diamond Shark merchants, where it was used sporadically by Clans Hell’s Horses and Snow Raven.

Game Rules:
When functional, ProtoMechs may use the magnetic clamp system to mount any BattleMech (Omni or otherwise) per the Mechanized Battle Armor rules. However, a BattleMech may carry no more than two standard-size ProtoMechs in this fashion, with the carried ProtoMechs “occupying” the front or rear Center Torso locations only. If the ProtoMech weighs more than 9 tons, only one may be carried via the MCS, and must mount up on the ’Mech’s front Center Torso location.

If the ’Mech receives damage to a location where a ProtoMech is mounted, only half of the attack’s damage (round down) will actually strike the ’Mech, while the remainder is applied to the ProtoMech in a random location—rerolling any Near Miss location results until this damage is resolved. A ProtoMech that is damaged while riding on a BattleMech in this fashion is immediately dismounted in the BattleMech’s current hex, and begins the next turn phase as a separate unit.

While transporting ProtoMechs, a BattleMech’s speed is reduced in accordance with the standard rules for carrying unprotected external cargo, using the total weight of the ProtoMechs being carried to compute the change in MP. OmniMechs—which can accommodate up to six battle-armored troopers without affecting their speed—subtract 3 tons from the weight of each ProtoMech (to a minimum of 0 tons) carried in this manner when computing the external cargo weight.

ProtoMechs may not be transported by vehicles or aerospace units, even if such units are Omnis.

Any critical hits to a ProtoMech’s torso automatically destroy the MCS.

Special Unit Abilities
The special unit abilities described here are intended for use with the Alpha Strike rule system:
 Magnetic Clamp System (MCS)
ProtoMechs with magnetic clamps may ride on a BattleMech as if they were a battle armor infantry unit with the XMEC special. No more than 2 ProtoMechs with the MCS special may ride on a single transporting ’Mech at the same time.

When transporting ProtoMechs via the MCS special, the transport ’Mech will lose 2 inches of Move, per ProtoMech, so long as the ProtoMechs remain attached to it.

 Magnetic Clamp System (UCS)
ProtoMechs with magnetic clamps may ride on a BattleMech as if they were a battle armor infantry unit with the XMEC special. No more than 1 ProtoMech with the UCS special may ride on a single transporting ’Mech at the same time.

When transporting ProtoMechs via the UCS special, the transport ’Mech will lose 2 inches of Move, per ProtoMech, so long as the ProtoMechs remain attached to it.
