By Xotl's request from the errata discussion thread I'm reposting my errata report that did not end up in latest errata document:
P. 102 - Machine guns - Rapid-Fire Mode
Problem: It is not clear how much ammo is consumed, and heat produced if rapid-fire machine guns are used against conventional infantry.
Solution: Change the first sentence of the third paragraph to something like "Rapid-fire machine guns do not inflict increased damage on conventional infantry, though they consume ammo, and produce heat as described above when used against it." - see
http://bg.battletech.com/forums/index.php?topic=59547.0 for confirmation.

P. 341 Specialized Infantry (Cont.)
Problem: Minor formatting issue. TAG Troops are described between Paratroops and SCUBA units. To keep expected (mostly alphabetical, but with motorized and mechanized infantry after other sorts of infantry, as they are usually listed in the books) sequence they should be listed after SCUBA units.
Solution: Move entry for TAG Troops bellow SCUBA (Mechanized).
P. 341 Specialized Infantry Types Table
Problem: The table fails to explain, that each TAG weighs 20 kg (as discussed in
http://bg.battletech.com/forums/index.php?topic=56272.0).
Solution: Change "Added Tons (per Trooper)" for TAG Troops from 0.0 to 0.02. Possibly add a footnote explaining that this weight (and 0.05 tons of weight under Paramedics) are counted only for troopers carrying relevant equipment.
Problem 2: The *** footnote under the table seems to suggest that TAG Troops only function if TAGs are assigned to a
minimum 2 troopers per squad, but under TM rules a squad can only have up to 2 troopers with support weapons (which TAG-equipped troopers substitute), so word "minimum" is redundant. Also putting that note in the Prohibited Terrain column makes no sense, as it has nothing to do with movement.
Solution 2: Either delete word "minimum" in the footnote and move "***" mark in the TAG Troops line from the last to the second (or possibly first) column, or delete an entire footnote and explain how TAG Troops platoons are constructed - including answering my question weather you need to assign TAGs to all squads or only one squad in the platoon (see
http://bg.battletech.com/forums/index.php?topic=59506.0).
Problem 3: Minor formatting issues. TAG Troops are listed in the table between Paratroops and Paramedics. For reasons explained under "P. 341 Specialized Infantry (Cont.)" above they should be listed at the bottom of the table. Also entries for Paratroops and Paramedics should be swapped to keep alphabetical sequence.
Solution 3: Move the line for TAG Troops bellow the SCUBA (Mechanized) line. Move the line for Paratroops bellow the Paramedics line.
Pp. 412-413 Conventional Infantry Combat Data and Infantry Construction Data tables
Problem: The table lacks entry for TAG Troopers, and SCUBA (Mechanized).
Solution: Add the entry for "SCUBA (Mechanized)" and "TAG Troops" under Specialized Infantry (between "SCUBA (Motorized)" and "Xenoplanetary Condition-Trained Troops"). Most values that should go into the tables are either obvious or can be found in the Specialized Infantry Types Table on p. 341. Some like in "Cost (C-bolls)" and "Latest Intro Date (IS/Clan)" can probably be interpreted from AtoW (in particular p. 275 AtoW for TAG Troopers). Some may require designers decision. In particular I'm not certain where to find stats for those two columns for SCUBA (Motorized) units.
Problem 2: The weights in WT(kg) table don't match those in the Specialized Infantry Types table on p. 341. The weights on p. 341 are probably correct, and those on p. 413 are 1000 times to small.
Solution 2: In the Infantry Construction Data table on p. 413 in the WT (kg) column +1.4/trooper to +1400/trooper, +1.9/trooper to +1900/trooper, +0.1/trooper to +100/trooper and so on OR change the name of the column from WT (kg) to WT (tons). The first way is probably preferred, as it keeps the table in line with the Battle Armor Construction Data table above.
